IDL 8.0: How to update IMAGE data? [message #71912]

Dear Folks,

I'd like to update the data in an IDL 8.0 IMAGE graphic.
What's the "right" way to do this?

I've been doing things like

a = dist(256)
b = -a
im = image(a)
im = image(b,/OVERPLOT)

which works, but just feels wrong to me.

I was expecting to be able to do things like

im = image(a)
im.DATA = b

and have the image update properly. But apparently
I'm missing something, and this doesn't work.

Any thoughts?

TTFN,

David
