Well, until you need to do interactive 3-D graphics, in which case object
graphics are really the only solution.

I have not been a fan of the iTools, in particular, but they are improving
(although the documentation is still rather opaque).

This is pretty slick:

n = 10000
b = 1.0
eps = 0.5
x = RANDOMN(seed, n)
y = b*x + eps*RANDOMN(seed, n)
z = b*x + eps*RANDOMN(seed, n)
iPlot, x, y, z, /SCATTER, /NO_SAVEPROMPT

Real, 3-D, interactive scatterplots (among other things).

Plus, you can save the visualization as a .isv file. Anyone with IDL can open
it and view the visualization interactively.

Printing remains a real problem, though. I can capture a bitmap of the screen,
but I have never been able to create a usable Postscript file from an iTool. (I
can send it to the printer, but that is not much use for creating publications.)
