plbin: Plot a histogram from binned data
DESCRIPTION:
This function is not used in any examples.
SYNOPSIS:
plbin(nbin, x, y, opt)
ARGUMENTS:
nbin (PLINT, input) : Number of bins (i.e., number of values in x
and y arrays.)
x (const PLFLT *, input) : Pointer to array containing values
associated with bins. These must form a strictly increasing
sequence.
y (const 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).
