You have been getting some good advice, but I have
to admit I don't even understand some of it, and I've
been around for awhile. :-)

If *I* were a beginner, and I wanted to make a really
nice looking plot without having to know much about
anything (and in particular, how IDL really works!),
I grab the MPI_PLOT program and pass my data to that.
There are so many options there (including all manner
of output options) that you can get to just by pointing
and clicking, that even a beginner can get a great looking
plot in a couple of minutes. For higher resolution, just
make the window bigger. :-)

Use it like this:

IDL> MPI_Plot, mydata

It is a wrapper for the PLOT command (and much more).

Cheers,

David
