Nice graphs shows up but no file.ps was however created where it was suppose to or anywhere on my computer. I then installed ghostscript and then the imagemagick. I got the path to the 'convert' file into the idl path. Restarting IDL after each step to be sure.

There is a PS keyword on the program. To make a PostScript file you type
this:
IDL> Example, /PS
Otherwise, the output goes to the display.

Well, I'm guessing a Mac. That causes many a problem with getting
ImageMagick installed properly. Here is an article that explains the
problem:

I've no idea why the text is extremely small in the PostScript file.
But, I did notice in your original code that you had the font size so
large than it nearly took over the page when I ran your code. So maybe
something is radically different with our two machines with regard to
fonts. In any case, adjusting the font size in the program will help.
:-)
Cheers,
