plcon2
: Contour plot, general 2-d mapping for
fortran
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 caller only.
The C user should instead call plcont
using the built-in
transformation function pltr2
for the same
capability.
