plcon2: Contour plot, general 2-d mapping for
Fortran 77
Draws a contour plot of the data in
z[nx][ny],
using the nlevel contour
levels specified by clevel.
Only the region of the array from
kx to
lx and from
ky to
ly is plotted out. The
arrays xg and
yg are used to specify the
transformation between array indices and world coordinates. See
the Section called Contour and Shade Plots in Chapter 3 for more information.

NOTE: this function is intended for use from a Fortran 77 caller only.
The C user should instead call plcont using the built-in
transformation function pltr2 for the same
capability.
