%feature( "docstring", "Advance the (sub-)page

DESCRIPTION:

    Advances to the next subpage if sub=0, performing a page advance if
    there are no remaining subpages on the current page.  If subpages
    aren't being used, pladv(0) will always advance the page.  If sub>0,
    PLplot switches to the specified subpage.  Note that this allows you
    to overwrite a plot on the specified subpage; if this is not what you
    intended, use pleop followed by plbop to first advance the page.  This
    routine is called automatically (with sub=0) by plenv, but if plenv is
    not used, pladv must be called after initializing PLplot but before
    defining the viewport.

DESCRIPTION:

    Draws a box around the currently defined viewport with arbitrary
    world-coordinate origin specified by x0 and y0 and labels it with
    world coordinate values appropriate to the window.	Thus plaxes should
    only be called after defining both viewport and window.  The character
    strings xopt and yopt specify how the box should be drawn as described
    below.  If ticks and/or subticks are to be drawn for a particular
    axis, the tick intervals and number of subintervals may be specified
    explicitly, or they may be defaulted by setting the appropriate
    arguments to zero.

    y0 (PLFLT, input) :    World Y coordinate of origin. 

    xopt (const char *, input) :    Pointer to character string specifying

    combination of the following letters (upper or lower case) in any
    order: a: Draws axis, X-axis is horizontal line (y=0), and Y-axis
    is vertical line (x=0). 
        b: Draws bottom (X) or left (Y) edge of frame. 
        c: Draws top (X) or right (Y) edge of frame.

        g: Draws a grid at the major tick interval. 
        h: Draws a grid at the minor tick interval. 
        i: Inverts tick marks, so they are drawn outwards, rather than
        inwards. 
        l: Labels axis logarithmically.  This only affects the labels,
        not the data, and so it is necessary to compute the logarithms
        of data points before passing them to any of the drawing
        routines. 
        m: Writes numeric labels at major tick intervals in the
        unconventional location (above box for X, right of box for Y).

        also specified. 
        t: Draws major ticks.

    base of the graph, rather than parallel to the axis. 


    ytick (PLFLT, input) :    World coordinate interval between major
    ticks on the y axis. If it is set to zero, PLplot automatically
    generates a suitable tick interval.

%feature( "docstring", "Plot a histogram from binned data 

DESCRIPTION:

    Plots a histogram consisting of nbin bins.	The value associated with
    the i'th bin is placed in x[i], and the number of points in the bin is
    placed in y[i].  For proper operation, the values in x[i] must form a
    strictly increasing sequence.  By default, x[i] is the left-hand edge
    of the i'th bin. If opt=PL_BIN_CENTRED is used, the bin boundaries are
    placed midway between the values in the x array.  Also see plhist for
    drawing histograms from unbinned data. 

    Redacted form:  General: plbin(x, y, opt)
	    Perl/PDL: plbin(nbin, x, y, opt)

SYNOPSIS:

plbin(nbin, x, y, opt)

ARGUMENTS:

    nbin (PLINT, input) :    Number of bins (i.e., number of values in x
    and y arrays.) 

    x (PLFLT *, input) :    Pointer to array containing values associated
    with bins.  These must form a strictly increasing sequence. 

    y (PLFLT *, input) :    Pointer to array containing number of points
    in bin.  This is a PLFLT (instead of PLINT) array so as to allow
    histograms of probabilities, etc. 

    opt (PLINT, input) :    Is a combination of several flags:
    opt=PL_BIN_DEFAULT: The x represent the lower bin boundaries, the
    outer bins are expanded to fill up the entire x-axis and bins of
    zero height are simply drawn. 
        opt=PL_BIN_CENTRED|...: The bin boundaries are to be midway
        between the x values. If the values in x are equally spaced,
        the values are the center values of the bins. 
        opt=PL_BIN_NOEXPAND|...: The outer bins are drawn with equal
        size as the ones inside. 
        opt=PL_BIN_NOEMPTY|...: Bins with zero height are not drawn
        (there is a gap for such bins).

%feature( "docstring", "Begin a new page

DESCRIPTION:

    Begins a new page.	For a file driver, the output file is opened if
    necessary.	Advancing the page via pleop and plbop is useful when a
    page break is desired at a particular point when plotting to subpages.
     Another use for pleop and plbop is when plotting pages to different
    files, since you can manually set the file name by calling plsfnam
    after the call to pleop. (In fact some drivers may only support a
    single page per file, making this a necessity.)  One way to handle
    this case automatically is to page advance via pladv, but enable
    familying (see plsfam) with a small limit on the file size so that a
    new family member file will be created on each page break.

SYNOPSIS:

ARGUMENTS:

    rx (PLFLT, input) :    Input relative device coordinate (ranging from
    0. to 1.) for the x coordinate. 

    ry (PLFLT, input) :    Input relative device coordinate (ranging from
    0. to 1.) for the y coordinate. 

    wx (PLFLT *, output) :    Pointer to the returned world coordinate for
    x corresponding to the relative device coordinates rx and ry. 

    wy (PLFLT *, output) :    Pointer to the returned world coordinate for

    window (PLINT *, output) :      Pointer to the returned last defined
    window index that corresponds to the input relative device
    coordinates (and the returned world coordinates).  To give some
    background on the window index, for each page the initial window
    index is set to zero, and each time plwind is called within the
    page, world and device coordinates are stored for the window and
    the window index is incremented.  Thus, for a simple page layout
    with non-overlapping viewports and one window per viewport, window
    corresponds to the viewport index (in the order which the
    viewport/windows were created) of the only viewport/window
    corresponding to rx and ry.  However, for more complicated layouts
    with potentially overlapping viewports and possibly more than one
    window (set of world coordinates) per viewport, window and the
    corresponding output world coordinates corresponds to the last
    window created that fulfills the criterion that the relative
    device coordinates are inside it.  Finally, in all cases where the
    input relative device coordinates are not inside any
    viewport/window, then window is set to -1.

    This function is used in examples 12 and 21. 



SYNOPSIS:

plcol1(col1)

ARGUMENTS:

    col1 (PLFLT, input) :    This value must be in the range from 0. to 1.
    and is mapped to color using the continuous map1 color palette
    which by default ranges from blue to the background color to red. 
    The map1 palette can also be straightforwardly changed by the user

%feature( "docstring", "Plot color bar for image, shade or gradient plots 

DESCRIPTION:

    Routine for creating a continuous color bar for image, shade, or
    gradient plots. (See pllegend for similar functionality for creating
    legends with discrete elements). The arguments of plcolorbar provide
    control over the location and size of the color bar as well as the
    location and characteristics of the elements (most of which are
    optional) within that color bar.  The resulting color bar is clipped
    at the boundaries of the current subpage. (N.B. the adopted coordinate
    system used for some of the parameters is defined in the documentation
    of the position parameter.) 

    Redacted form: plcolorbar(p_colorbar_width, p_colorbar_height,  opt,
    position, x, y, x_length, y_length, bg_color, bb_color, bb_style,
    low_cap_color, high_cap_color, cont_color, cont_width, label_opts,
    labels, axis_opts, ticks, sub_ticks, values)

    This function is used in examples 16 and 33. 



SYNOPSIS:

plcolorbar(p_colorbar_width, p_colorbar_height, opt, position, x, y, x_length, y_length, bg_color, bb_color, bb_style, low_cap_color, high_cap_color, cont_color, cont_width, n_labels, label_opts, labels, naxes, axis_opts, ticks, sub_ticks, n_values, values)

ARGUMENTS:

    p_colorbar_width (PLFLT *, output) :    Pointer to a location which
    contains (after the call) the labelled and decorated color bar
    width in adopted coordinates. 

    p_colorbar_height (PLFLT *, output) :    Pointer to a location which
    contains (after the call) the labelled and decorated color bar
    height in adopted coordinates. 

    opt (PLINT, input) :    opt contains bits controlling the overall
    color bar.  The orientation (direction of the maximum value) of
    the color bar is specified with PL_ORIENT_RIGHT, PL_ORIENT_TOP,
    PL_ORIENT_LEFT, or PL_ORIENT_BOTTOM.  If none of these bits are
    specified, the default orientation is toward the top if the
    colorbar is placed on the left or right of the viewport or toward
    the right if the colorbar is placed on the top or bottom of the
    viewport. If the PL_COLORBAR_BACKGROUND bit is set, plot a
    (semi-transparent) background for the color bar. If the
    PL_COLORBAR_BOUNDING_BOX bit is set, plot a bounding box for the
    color bar. The type of color bar must be specified with one of
    PL_COLORBAR_IMAGE, PL_COLORBAR_SHADE, or PL_COLORBAR_GRADIENT. If
    more than one of those bits is set only the first one in the above
    list is honored. The position of the (optional) label/title can be
    specified with PL_LABEL_RIGHT, PL_LABEL_TOP, PL_LABEL_LEFT, or
    PL_LABEL_BOTTOM.  If no label position bit is set then no label
    will be drawn. If more than one of this list of bits is specified,
    only the first one on the list is honored. End-caps for the color
    bar can added with PL_COLORBAR_CAP_LOW and PL_COLORBAR_CAP_HIGH.
    If a particular color bar cap option is not specified then no cap
    will be drawn for that end. As a special case for
    PL_COLORBAR_SHADE, the option PL_COLORBAR_SHADE_LABEL can be
    specified. If this option is provided then any tick marks and tick
    labels will be placed at the breaks between shaded segments. TODO:
    This should be expanded to support custom placement of tick marks
    and tick labels at custom value locations for any color bar type. 

    position (PLINT, input) :     position contains bits which control the
    overall position of the color bar and the definition of the
    adopted coordinates used for positions just like what is done for
    the position argument for pllegend. However, note that the
    defaults for the position bits (see below) are different than the
    pllegend case. The combination of the PL_POSITION_LEFT,
    PL_POSITION_RIGHT, PL_POSITION_TOP, PL_POSITION_BOTTOM,
    PL_POSITION_INSIDE, and PL_POSITION_OUTSIDE bits specifies one of
    the 16 possible standard positions (the 4 corners and centers of
    the 4 sides for both the inside and outside cases) of the color
    bar relative to the adopted coordinate system. The corner
    positions are specified by the appropriate combination of two of
    the PL_POSITION_LEFT, PL_POSITION_RIGHT, PL_POSITION_TOP, and
    PL_POSITION_BOTTOM bits while the sides are specified by a single
    value of one of those bits.  The adopted coordinates are
    normalized viewport coordinates if the PL_POSITION_VIEWPORT bit is
    set or normalized subpage coordinates if the PL_POSITION_SUBPAGE
    bit is set. Default position bits: If none of PL_POSITION_LEFT,
    PL_POSITION_RIGHT, PL_POSITION_TOP, or PL_POSITION_BOTTOM are set,
    then use PL_POSITION_RIGHT. If neither of PL_POSITION_INSIDE or
    PL_POSITION_OUTSIDE is set, use PL_POSITION_OUTSIDE. If neither of
    PL_POSITION_VIEWPORT or PL_POSITION_SUBPAGE is set, use
    PL_POSITION_VIEWPORT. 

    x (PLFLT, input) :      X offset of the color bar position in adopted
    coordinates from the specified standard position of the color bar.
    For positive x, the direction of motion away from the standard
    position is inward/outward from the standard corner positions or
    standard left or right positions if the
    PL_POSITION_INSIDE/PL_POSITION_OUTSIDE bit is set in position. 
    For the standard top or bottom positions, the direction of motion
    is toward positive X. 

    y (PLFLT, input) :      Y offset of the color bar position in adopted
    coordinates from the specified standard position of the color bar.
    For positive y, the direction of motion away from the standard
    position is inward/outward from the standard corner positions or
    standard top or bottom positions if the
    PL_POSITION_INSIDE/PL_POSITION_OUTSIDE bit is set in position. 
    For the standard left or right positions, the direction of motion
    is toward positive Y. 

    x_length (PLFLT, input) :     Length of the body of the color bar in
    the X direction in adopted coordinates. 

    y_length (PLFLT, input) :     Length of the body of the color bar in
    the Y direction in adopted coordinates. 

    bg_color (PLINT, input) :     The cmap0 color of the background for the
    color bar (PL_COLORBAR_BACKGROUND). 

    bb_color (PLINT, input) :     The cmap0 color of the bounding-box line
    for the color bar (PL_COLORBAR_BOUNDING_BOX). 

    bb_style (PLINT, input) :     The pllsty style number for the
    bounding-box line for the color bar (PL_COLORBAR_BACKGROUND). 

    low_cap_color (PLFLT, input) :    The cmap1 color of the low-end color
    bar cap, if it is drawn (PL_COLORBAR_CAP_LOW). 

    high_cap_color (PLFLT, input) :    The cmap1 color of the high-end
    color bar cap, if it is drawn  (PL_COLORBAR_CAP_HIGH). 

    cont_color (PLINT, input) :    The cmap0 contour color for
    PL_COLORBAR_SHADE plots. This is passed directly to plshades, so
    it will be interpreted according to the design of plshades. 

    cont_width (PLFLT, input) :    Contour width for PL_COLORBAR_SHADE
    plots. This is passed directly to plshades, so it will be
    interpreted according to the design of plshades. 

    n_labels (PLINT, input) :     Number of labels to place around the
    color bar. 

    label_opts (const PLINT *, input) :    Options for each of 
    n_labels labels. 

    labels (const char *const *, input) :    n_labels text labels for the
    color bar. No label is drawn if no label position is specified
    with one of the PL_COLORBAR_LABEL_RIGHT, PL_COLORBAR_LABEL_TOP,
    PL_COLORBAR_LABEL_LEFT, or PL_COLORBAR_LABEL_BOTTOM bits in the
    corresponding label_opts field. 

    n_axes (PLINT, input) :    Number of axis definitions provided. This
    value must be greater than 0. It is typically 1 (numerical axis
    labels are provided for one of the long edges of the color bar),
    but it can be larger if multiple numerical axis labels for the
    long edges of the color bar are desired. 

    axis_opts (const char *const *, input) :    An array of n_axes axis
    options (interpreted as for plbox) for the color bar's axis
    definitions. 

    ticks (PLFLT *, input) :    An array of n_axes values of the spacing
    of the major tick marks (interpreted as for plbox) for the color
    bar's axis definitions. 

    sub_ticks (PLINT *, input) :    An array of n_axes values of the
    number of subticks (interpreted as for plbox) for the color bar's
    axis definitions. 

    n_values (PLINT, input) :     An array containing the number of
    elements in each of the n_axes rows of the two-dimensional values
    array. 

    values (PLFLT *const *, input) :    A two-dimensional array containing
    the numeric values for the data range represented by the color
    bar. For a row index of i_axis (where 0 < i_axis < n_axes), the
    number of elements in the row is specified by n_values[i_axis].
    For PL_COLORBAR_IMAGE and PL_COLORBAR_GRADIENT the number of
    elements is 2, and the corresponding row elements of the values
    array are the minimum and maximum value represented by the
    colorbar.  For PL_COLORBAR_SHADE, the number and values of the
    elements of a row of the values array is interpreted the same as
    the nlevel and clevel arguments of plshades.

ARGUMENTS:

    z (PLFLT **, input) :    Pointer to a vectored two-dimensional array
    containing data to be contoured. 

    nx, ny (PLINT, input) :    Physical dimensions of array z. 

    kx, lx (PLINT, input) :    Range of x indices to consider. 

    ky, ly (PLINT, input) :    Range of y indices to consider. 

    clevel (PLFLT *, input) :     Pointer to array specifying levels at
    which to draw contours. 

    nlevel (PLINT, input) :    Number of contour levels to draw. 

    pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input) : 
      Pointer to function that defines transformation between indices
    in array z and the world coordinates (C only).    Transformation
    functions are provided in the PLplot library: pltr0 for identity
    mapping, and pltr1 and pltr2 for arbitrary mappings respectively
    defined by one- and two-dimensional arrays.  In addition,
    user-supplied routines for the transformation can be used as well.
     Examples of all of these approaches are given in the PLplot
    documentation. The transformation function should have the form
    given by any of pltr0, pltr1, or pltr2. Note that unlike plshades
    and similar PLplot functions which have a pltr argument, plcont
    requires that a transformation function be provided in the C
    interface.  Leaving  pltr NULL will result in an error.

    xg (PLFLT *, input) :    The input array that specifies the grid
    spacing in the x direction. Usually xg has nptsx equally spaced
    values from the minimum to the maximum values of the x input
    array. 

    nptsx (PLINT, input) :    The number of points in the xg array. 

    yg (PLFLT *, input) :    The input array that specifies the grid

    This function is used in examples 4, 26, and 33. 



SYNOPSIS:

ARGUMENTS:

    p_legend_width (PLFLT *, output) :      Pointer to a location which
    contains (after the call) the legend width in adopted coordinates.
    This quantity is calculated from plot_width, text_offset, ncolumn
    (possibly modified inside the routine depending on nlegend and
    nrow), and the length (calculated internally) of the longest text
    string. 

    p_legend_height (PLFLT *, output) :    Pointer to a location which
    contains (after the call) the legend height in adopted
    coordinates. This quantity is calculated from text_scale,
    text_spacing, and nrow (possibly modified inside the routine
    depending on nlegend and nrow). 

    opt (PLINT, input) :    opt contains bits controlling the overall
    legend. If the PL_LEGEND_TEXT_LEFT bit is set, put the text area
    on the left of the legend and the plotted area on the right.
    Otherwise, put the text area on the right of the legend and the
    plotted area on the left. If the PL_LEGEND_BACKGROUND bit is set,
    plot a (semi-transparent) background for the legend. If the
    PL_LEGEND_BOUNDING_BOX bit is set, plot a bounding box for the
    legend. If the PL_LEGEND_ROW_MAJOR bit is set and (both of the
    possibly internally transformed) nrow > 1 and ncolumn > 1, then
    plot the resulting array of legend entries in row-major order.
    Otherwise, plot the legend entries in column-major order. 

    position (PLINT, input) :     position contains bits which control the
    overall position of the legend and the definition of the adopted
    coordinates used for positions just like what is done for the
    position argument for plcolorbar. However, note that the defaults
    for the position bits (see below) are different than the
    plcolorbar case.  The combination of the PL_POSITION_LEFT,
    PL_POSITION_RIGHT, PL_POSITION_TOP, PL_POSITION_BOTTOM,
    PL_POSITION_INSIDE, and PL_POSITION_OUTSIDE bits specifies one of
    the 16 possible standard positions (the 4 corners and centers of
    the 4 sides for both the inside and outside cases) of the legend
    relative to the adopted coordinate system. The corner positions
    are specified by the appropriate combination of two of the
    PL_POSITION_LEFT, PL_POSITION_RIGHT, PL_POSITION_TOP, and
    PL_POSITION_BOTTOM bits while the sides are specified by a single
    value of one of those bits.  The adopted coordinates are
    normalized viewport coordinates if the PL_POSITION_VIEWPORT bit is
    set or normalized subpage coordinates if the PL_POSITION_SUBPAGE
    bit is set. Default position bits: If none of PL_POSITION_LEFT,
    PL_POSITION_RIGHT, PL_POSITION_TOP, or PL_POSITION_BOTTOM are set,
    then use the combination of PL_POSITION_RIGHT and PL_POSITION_TOP.
    If neither of PL_POSITION_INSIDE or PL_POSITION_OUTSIDE is set,
    use PL_POSITION_INSIDE. If neither of PL_POSITION_VIEWPORT or
    PL_POSITION_SUBPAGE is set, use PL_POSITION_VIEWPORT. 

    x (PLFLT, input) :      X offset of the legend position in adopted
    coordinates from the specified standard position of the legend.
    For positive x, the direction of motion away from the standard
    position is inward/outward from the standard corner positions or
    standard left or right positions if the
    PL_POSITION_INSIDE/PL_POSITION_OUTSIDE bit is set in position. 
    For the standard top or bottom positions, the direction of motion
    is toward positive X. 

    y (PLFLT, input) :      Y offset of the legend position in adopted
    coordinates from the specified standard position of the legend.
    For positive y, the direction of motion away from the standard
    position is inward/outward from the standard corner positions or
    standard top or bottom positions if the
    PL_POSITION_INSIDE/PL_POSITION_OUTSIDE bit is set in position. 
    For the standard left or right positions, the  direction of motion
    is toward positive Y. 

    plot_width (PLFLT, input) :    Horizontal width in adopted coordinates
    of the plot area (where the colored boxes, lines, and/or lines of
    symbols are drawn) of the legend. 

    bg_color (PLINT, input) :     The cmap0 color of the background for the
    legend (PL_LEGEND_BACKGROUND). 

    bb_color (PLINT, input) :     The cmap0 color of the bounding-box line
    for the legend (PL_LEGEND_BOUNDING_BOX). 

    bb_style (PLINT, input) :     The pllsty style number for the
    bounding-box line for the legend (PL_LEGEND_BACKGROUND). 

    nrow (PLINT, input) :    The cmap0 index of the background color for
    the legend (PL_LEGEND_BACKGROUND). 

    ncolumn (PLINT, input) :    The cmap0 index of the background color
    for the legend (PL_LEGEND_BACKGROUND). 

    nlegend (PLINT, input) :    Number of legend entries.  N.B.  The total
    vertical height of the legend in adopted coordinates is calculated
    internally from nlegend, text_scale (see below), and text_spacing
    (see below). 

    opt_array (const PLINT *, input) :      Array of nlegend values of
    options to control each individual plotted area corresponding to a
    legend entry.  If the 
    PL_LEGEND_NONE bit is set, then nothing is plotted in the plotted
    area.  If the 
    PL_LEGEND_COLOR_BOX, 
    PL_LEGEND_LINE, and/or 
    PL_LEGEND_SYMBOL bits are set, the area corresponding to a legend
    entry is plotted with a colored box; a line; and/or a line of
    symbols. 

    text_offset (PLFLT, input) :    Offset of the text area from the plot
    area in units of character width.  N.B.  The total horizontal
    width of the legend in adopted coordinates is calculated
    internally from 
    plot_width (see above), 
    text_offset, and length (calculated internally) of the longest text
    string. 

    text_scale (PLFLT, input) :    Character height scale for text
    annotations.  N.B.  The total vertical height of the legend in
    adopted coordinates is calculated internally from 
    nlegend (see above), 
    text_scale, and 
    text_spacing (see below). 

    text_spacing (PLFLT, input) :    Vertical spacing in units of the
    character height from one legend entry to the next.  N.B.  The
    total vertical height of the legend in adopted coordinates is
    calculated internally from 
    nlegend (see above), 
    text_scale (see above), and 
    text_spacing. 

    text_justification (PLFLT, input) :    Justification parameter used
    for text justification.  The most common values of
    text_justification are 0., 0.5, or 1. corresponding to a text that
    is left justified, centred, or right justified within the text
    area, but other values are allowed as well. 

    text_colors (const PLINT *, input) :    Array of nlegend cmap0 text
    colors. 

    text (const char *const *, input) :    Array of nlegend text string
    annotations. 

    box_colors (const PLINT *, input) :    Array of nlegend cmap0 colors

%feature( "docstring", "Draw a polygon in 3 space 

DESCRIPTION:

    Draws a polygon in 3 space defined by n points in x, y, and z. Setup
    like plline3, but differs from that function in that plpoly3 attempts
    to determine if the polygon is viewable depending on the order of the
    points within the arrays and the value of ifcc.  If the back of
    polygon is facing the viewer, then it isn't drawn.	If this isn't what
    you want, then use plline3 instead. 

    The points are assumed to be in a plane, and the directionality of the
    plane is determined from the first three points.  Additional points do
    not have to lie on the plane defined by the first three, but if they
    do not, then the determination of visibility obviously can't be 100%
    accurate... So if you're 3 space polygons are too far from planar,
    consider breaking them into smaller polygons.  3 points define a plane
    :-). 

    Bugs:  If one of the first two segments is of zero length, or if they
    are co-linear, the calculation of visibility has a 50/50 chance of
    being correct.  Avoid such situations :-).	See x18c.c for an example
    of this problem. (Search for 20.1).

%feature( "docstring", "Set color map1 colors using a piece-wise linear relationship 

DESCRIPTION:

    Set color map1 colors using a piece-wise linear relationship between
    position in the color map (from 0 to 1) and position in HLS or RGB
    color space (see the PLplot documentation).  May be called at any
    time. 

    The idea here is to specify a number of control points that define the
    mapping between palette 1 input positions (intensities) and  HLS (or
    RGB).  Between these points, linear interpolation is used which gives
    a smooth variation of color with input position.  Any number of
    control points may be specified, located at arbitrary positions,
    although typically 2 - 4 are enough. Another way of stating this is
    that we are traversing a given number of lines through HLS (or RGB)
    space as we move through color map1 entries.  The control points at
    the minimum and maximum position (0 and 1) must always be specified. 
    By adding more control points you can get more variation.  One good
    technique for plotting functions that vary about some expected average
    is to use an additional 2 control points in the center (position ~=
    0.5) that are the same lightness as the background (typically white
    for paper output, black for crt), and same hue as the boundary control
    points.  This allows the highs and lows to be very easily
    distinguished. 

    Each control point must specify the position in color map1 as well as
    three coordinates in HLS or RGB space.  The first point must
    correspond to position = 0, and the last to position = 1. 

    The default behaviour is for the hue to be linearly interpolated 
    between the control points. Since the hue lies in the range [0, 360]
    this corresponds to interpolation around the \"front\" of the color
    wheel (red<->green<->blue<->red). If alt_hue_path[i] is true, then an
    alternative interpolation is used between control points i and i+1. If
     hue[i+1]-hue[i] > 0 then interpolation is between	hue[i] and
    hue[i+1] - 360, otherwise  between hue[i] and hue[i+1] + 360.  You can
    consider this as interpolation around the \"back\" or \"reverse\" of  the
    color wheel. Specifying alt_hue_path=NULL is equivalent to setting
    alt_hue_path[] = false for	every control point.

    and hence larger image sizes. For png values are in the range -1
    to 99. Values of 0-9 are taken as the  compression level for zlib.
    A value of -1 denotes the default zlib    compression level. Values
    in the range 10-99 are divided by 10 and  then used as the zlib
    compression level. Higher compression levels correspond to greater

ARGUMENTS:

    a (PLFLT **, input) :    Contains ** pointer to array to be plotted.
    The array must have been declared as PLFLT a[nx][ny]. 

    nx (PLINT, input) :    First dimension of array \"a\". 

    ny (PLINT, input) :    Second dimension of array \"a\". 

    defined (PLINT (*) (PLFLT, PLFLT), input) :    User function
    specifying regions excluded from the shading plot.  This function
    accepts x and y coordinates as input arguments and must return 0
    if the point is in the excluded region or 1 otherwise. This
    argument can be NULL if all the values are valid. 

    xmin (PLFLT, input) :    Defines the \"grid\" coordinates.  The data
    a[0][0] has a position of (xmin,ymin), a[nx-1][0] has a position
    at (xmax,ymin) and so on. 

    xmax (PLFLT, input) :    Defines the \"grid\" coordinates.  The data
    a[0][0] has a position of (xmin,ymin), a[nx-1][0] has a position
    at (xmax,ymin) and so on. 

    ymin (PLFLT, input) :    Defines the \"grid\" coordinates.  The data
    a[0][0] has a position of (xmin,ymin), a[nx-1][0] has a position
    at (xmax,ymin) and so on. 

    ymax (PLFLT, input) :    Defines the \"grid\" coordinates.  The data
    a[0][0] has a position of (xmin,ymin), a[nx-1][0] has a position
    at (xmax,ymin) and so on. 

    clevel (PLFLT *, input) :     Pointer to array containing the data
    levels corresponding to the edges of each shaded region that will
    be plotted by this function.  To work properly the levels should
    be monotonic. 

    nlevel (PLINT, input) :    Number of shades plus 1 (i.e., the number
    of shade edge values in clevel). 

    fill_width (PLFLT, input) :    Defines line width used by the fill
    pattern. 

    cont_color (PLINT, input) :    Defines pen color used for contours
    defining edges of shaded regions.  The pen color is only temporary
    set for the contour drawing.  Set this value to zero or less if no
    shade edge contours are wanted. 

    cont_width (PLFLT, input) :    Defines line width used for contours
    defining edges of shaded regions.  This value may not be honored
    by all drivers. The pen width is only temporary set for the
    contour drawing.  Set this value to zero or less if no shade edge
    contours are wanted. 

    fill (void (*) (PLINT, PLFLT *, PLFLT *), input) :      Routine used to
    fill the region.  Use plfill.  Future version of PLplot may have
    other fill routines. 

    rectangular (PLBOOL, input) :    Set rectangular to true if rectangles
    map to rectangles after coordinate transformation with pltrl. 
    Otherwise, set rectangular to false. If rectangular is set to
    true, plshade tries to save time by filling large rectangles. 
    This optimization fails if the coordinate transformation distorts
    the shape of rectangles. For example a plot in polar coordinates
    has to have  rectangular set to false. 

    pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input) : 
      Pointer to function that defines transformation between indices
    in array z and the world coordinates (C only).    Transformation
    functions are provided in the PLplot library: pltr0 for identity
    mapping, and pltr1 and pltr2 for arbitrary mappings respectively
    defined by one- and two-dimensional arrays.  In addition,
    user-supplied routines for the transformation can be used as well.
     Examples of all of these approaches are given in the PLplot
    documentation. The transformation function should have the form
    given by any of pltr0, pltr1, or pltr2. 

    pltr_data (PLPointer, input) :    Extra parameter to help pass
    information to pltr0, pltr1, pltr2, or whatever routine that is
    externally supplied.

    a[0][0] has a position of (xmin,ymin), a[nx-1][0] has a position
    at (xmax,ymin) and so on. 

    shade_min (PLFLT, input) :      Defines the lower end of the interval to
    be shaded. If shade_max <= shade_min, plshade1 does nothing. 

    shade_max (PLFLT, input) :      Defines the upper end of the interval to
    be shaded. If shade_max <= shade_min, plshade1 does nothing. 

    sh_cmap (PLINT, input) :    Defines color map. If  sh_cmap=0, then
    sh_color is interpreted as a color map 0 (integer) index.  If 
    sh_cmap=1, then sh_color is interpreted as a color map 1
    floating-point index which ranges from 0. to 1.

    min_color (PLINT, input) :      Defines pen color, width used by the
    boundary of shaded region. The min values are used for the
    shade_min boundary, and the max values are used on the shade_max
    boundary.  Set color and width to zero for no plotted boundaries. 

    min_width (PLFLT, input) :      Defines pen color, width used by the
    boundary of shaded region. The min values are used for the
    shade_min boundary, and the max values are used on the shade_max

    fill the region.  Use plfill.  Future version of plplot may have
    other fill routines. 

    rectangular (PLBOOL, input) :    Set rectangular to true if rectangles
    map to rectangles after coordinate transformation with pltrl. 
    Otherwise, set rectangular to false. If rectangular is set to
    true, plshade tries to save time by filling large rectangles. 
    This optimization fails if the coordinate transformation distorts
    the shape of rectangles. For example a plot in polar coordinates
    has to have rectangular set to false. 

    pltr (void (*) (PLFLT, PLFLT, PLFLT *, PLFLT *, PLPointer) , input) : 
      Pointer to function that defines transformation between indices
    in array z and the world coordinates (C only).    Transformation
    functions are provided in the PLplot library: pltr0 for identity
    mapping, and pltr1 and pltr2 for arbitrary mappings respectively
    defined by one- and two-dimensional arrays.  In addition,
    user-supplied routines for the transformation can be used as well.
     Examples of all of these approaches are given in the PLplot
    documentation. The transformation function should have the form
    given by any of pltr0, pltr1, or pltr2. 

    pltr_data (PLPointer, input) :    Extra parameter to help pass
    information to pltr0, pltr1, pltr2, or whatever routine that is

DESCRIPTION:

    Sets the page configuration (optional).  If an individual parameter is

    The X-window driver uses the length and offset parameters to determine
    the window size and location.  The length and offset values are
    expressed in units that are specific to the current driver. For

    otherwise interfere with the plots.  The program must switch back to
    the graphics window before issuing plot commands, as the text (or
