Hi David,
The MPI_plot procedure is indeed very helpful. However, does it
support
things like xyouts?
For me, the most desirable feature for plotting is the ability to
print the
plot on a direct graphics window directly to ps/eps/printer. Retyping
all
the previous commands into ps/printer is truly tiresome, the worst
part is
when one makes a tiny mistake, everything must be redone from the
start!
While I noticed there are procedures like TVRead, the quality of
output is
not as good as I would like it to be.
I wish I will learn enough IDL to participate in the open source
project
one day...
