Check out the new procedure HEAP_GC to do garbage collection on
heap variables. First, though, make sure you're freeing your
pointers!

If you want to use a different drawing color for the background of the
plot (useful if you have a predefined color table that you don't want
to mess with), you can use
plot, x, y, background=255, color=some_color
You probably want to set the foreground color also, in
case !p.color is 255!
