Alright, in an ongoing effort to keep TVIMAGE and TVSCALE
as the number one TV replacements in the IDL universe,
I have added the ability to do what you want to do here.
Now, if you use the POSITION keyword with either TVIMAGE
or TVSCALE, and you are displaying images with !P.MULTI,
the POSITION keyword will position the image with respect
to the "window" specified for the image by !P.MULTI. (Since
no one in their right mind would be using the POSITION
keyword and !P.MULTI together, I figure this won't affect
anyone currently using the TVIMAGE command.)
So, to put four images and associated colorbars into a
window with !P.MULTI, you would write code something
like this:
;*********************************************************
image = Dist(200)
!P.Multi=[0,2,2]
p = [0.02, 0.3, 0.98, 0.98]
LoadCT, 0
TVImage, image, Position=p
Colorbar, Position=[p[0], p[1]-0.1, p[2], p[1]-0.05]
p = [0.02, 0.3, 0.98, 0.98]
LoadCT, 5
TVImage, image, Position=p
Colorbar, Position=[p[0], p[1]-0.1, p[2], p[1]-0.05]
p = [0.02, 0.3, 0.98, 0.98]
LoadCT, 2
TVImage, image, Position=p
Colorbar, Position=[p[0], p[1]-0.1, p[2], p[1]-0.05]
p = [0.02, 0.3, 0.98, 0.98]
LoadCT, 3
TVImage, image, Position=p
Colorbar, Position=[p[0], p[1]-0.1, p[2], p[1]-0.05]
!P.Multi = 0
