Tim: Thank you, that works great. Josef: I can plot 2D matrices with GR (which is what I want) but your code example doesn't work. GR looks pretty impressive, I'll have to check it out. A bit disappointed there's no interface to zoom in/out with the mouse and for some reason the window won't close.
Tom: Works for images but not readily clear how to plot something like rand(100,100) as a bitmap instead of a 100 lines. Do I have to convert it to an image structure for plot to figure out that it's a bitmap? Thanks, all!
