Just by pure curiosity: is this problem (displaying two images of
different aspect ratios + a colorbar in a line) anyhow easier in NG?

Hi David,

Thanks, I adapted your idea in my code and after a few dozens of tries I
am satisfied with the output ;-) I won't change anything at the code
anymore though!

Cheers,

Fabien

In the following I am making two plots with cg* routines.

img1 = cgDemoData(7)
img2 = congrid(img1, 360, 180)
cgDisplay, 900, 400
!P.Multi = [0, 2, 1]
multimargin = [1,1,1,1]
cgImage, img1, MULTIMARGIN=multimargin, /KEEP_ASPECT_RATIO, /AXES
cgImage, img2, MULTIMARGIN=multimargin, /KEEP_ASPECT_RATIO, /AXES
!P.Multi = 0

Nice, but I would like the top limit of the plots being the same
(meaning translate the second plot upwards a bit). I could'nt find an
easy solution. There must be one though! Any thoughts?

POSITION keyword. Heterogeneous positioning of plots is not the forte
of !P.MULTI, who is a guy who craves repetition and homogeneity. :-)

And, since you are asking to keep the aspect ratio, you will have to
be prepared to adjust the position of the second image in Y space.
I would probably try something like this.

;--------------------------------------------------
img1 = cgDemoData(7)
img2 = congrid(img1, 360, 180)
cgDisplay, 900, 400
cgImage, img1, /KEEP_ASPECT_RATIO, /AXES, $
POSITION=[0.05, 0.1, 0.475, 0.90], OPOSITION=op

s = Size(img2, /Dimensions)
imgaspect = Float(s[1])/s[0]

xdist = 0.95-0.525
ydist = (xdist * imgaspect) * 2
pos2 = [0.525, op[3]-ydist, 0.95, op[3]]
cgImage, img2, /AXES, POSITION=pos2, /NoErase
;--------------------------------------------------

Cheers,

David
