This solution
for i=0,24 do cgimage, im,xv=x,yv=x,/axis, color='dodger blue'
works like a charm, regardless of Device settings etc.
About the retain:
If i use:
Device, Retain=0
!p.multi=[0,5,5]
for i=0,24 do cgImage, im, /Axes & !p.multi=0
I get colors.
If i use
Device, Retain=2
!p.multi=[0,5,5]
for i=0,24 do cgImage, im, /Axes & !p.multi=0
I get colors
if i use
Device, Retain=2
cgDisplay
!p.multi=[0,5,5]
for i=0,24 do cgImage, im, /Axes & !p.multi=0
I don't get colors, but i have the other "bug" the first 4 plots have black axes and the others have white..
i get the same result if retain is set to 0, so i think that cgDisplay does some trick and solves the problem at some extent.
