Hi everyone.
I know there are ways to set the resolution for a plot in IDL when you are writing it into a PNG or PS file, but I am using plot3d (p = plot3d(x,y,z, '4.'), where x,y,z are some arrays) and can't write it into either of the above formats, and thus can't change its resolution. Any idea how I can do that?
Thanks,
Maryam

I'm not really sure I understand the issue. You can absolutely save your plot as a PNG:
x= (y= (z=randomn(1l, 100))
p=plot3d(x, y, z, '4')
p.save, 'test.png'
There are also all sorts of keywords, including one to specifically set the resolution.
