C+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
C
C
C Purpose
C This subroutine plots "data" defined on a regularly-spaced
C rectangular grid of points Z(I,J). With the default choice for the
C PGCELL routine that is linked, the output is a linearly-interpolated
C map (rather than coarse rectangular boxes).
C
C Parameters
C ARGUMENT TYPE I/O DIMENSION DESCRIPTION
C Z R*4 I N1 x N2 The recatangular "data"-array.
C Z R*4 O N1 x N2 A scaled, and clipped, version of
C the input array(!).
C N1 I*4 I - The first dimension of array Z.
C N2 I*4 I - The second dimension of array Z.
C X R*4 I NX Array of X-coordinates.
C NX I*4 I - Number of X-pixels to be plotted
C (usually = N1, but must be <= N1).
C Y R*4 I NY Array of Y-coordinates.
C NY I*4 I - Number of Y-pixels to be plotted
C (usually = N2, but must be <= N2).
C W R*4 I - Dummy parameter (back-compatibility).
C SIZE R*4 I - Character-size for plot (try 1.5).
C IWIDTH I*4 I - Line-width for plot (try 2).
C XLBL A*1 I *(*) Label for X-axis.
C YLBL A*1 I *(*) Label for Y-axis.
C TITL A*1 I *(*) Title for plot.
