Hello Folks,
some part of the sky is falling on me while trying to do a scatterplot
with an associated colorbar on a z-buffer device.
Here is what I do (shorted):
----------------
set_plot,'Z'
Device, Set_Resolution=[800,500], SET_PIXEL_DEPTH=24, DECOMPOPSED=1
Erase
cgLoadCt, 13
cgScatter2d, aziplot[0:79,*], aziplotv[0:79,*], axiscolor='black', $
Background='white', PSym=3, Fit=1, color=bytscl(t1), /GRID, $
XRange=[xlo,xhi], YRANGE=[ylo,yhi], $ Position=[0.1, 0.1, 0.75, 0.90]
cgColorBar, Range=[0, 80*25], /VERTICAL, /RIGHT
write_png, destpath + fname, tvrd(/true)
---------------
Problem is: The scatter plot has colors but the colorbar is only greyscale.
I flipped through the Traditional IDL Graphics and also searched over
the internet. I'am now aware that there may be a problem with color
decomposition. I tried to play around with the decomposition state but
with no avail. So I came to the conclusion that before the sky falls on
my head I address the experts in this group.
So here is my question: What do I have to do to get a colored colorbar?
What may be the sources auf the greyscale colorbar? Whats wrong?
IDL 7.1 fresh Install, Coyote Library also fresh, Linux System, no X!
Cheers,
Kai
