Hi,
I'm running code that used to properly deal with this issue but "all of a sudden", all of my plots are red again...for the first time in *years*.
I'm running IDL 7.0.6 (and not interested in upgrading) on Mac OS 10.8.5 and XQuartz 2.7.5.
Unfortunately, I haven't been using IDL regularly and lots of changes have probably been applied to my system since I last had regular display functionality. I suspect it's the new XQuartz?
thanks for any thoughts.

Hey David,
Thanks for the quick reply.
Yes, I'm aware of that command and have had it in my code and functioning for many years. It has recently *stopped* working.
IF ~KEYWORD_SET(ps) THEN BEGIN
;set up for display to screen
set_plot,'x'
device, Decomposed=0 ;make colors work for 24-bit display
print,'debug red plots'
ENDIF
If no one else has encountered this problem with the new XQuartz or Mac OS, I will try to debug some more on my own.
thanks!

I'd be curious to know what HELP, /DEVICE turns up. :-)

ok, I think I figured it out. I just needed to explicitly define the color of the plot (color_line). I've never needed to do this before, but it worked!
The annotations are all still red...guess I need to also explicitly give those colors in the xyouts commands.
What's the "default" color? Does it use whatever is assigned to 255? Cause if so, that would explain it. (And maybe I changed my custom color table? this is starting to ring some bells...)
kelle
@colors_kc ; loads custom color table gives colors names
color_line = black
IF ~KEYWORD_SET(ps) THEN BEGIN
;set up for display to screen
set_plot,'x'
device, Decomposed=0 ;make colors work for 24-bit display
print,'ye'
color_line=white
ENDIF
plot, w, spec, [...], color=color_line

yep, just needed to have white as the last color. It was just a coincidence that I had modified the color table to have red as color 255...thus mimicking the Device, Decomposed = 0 problem. sneaky, sneaky.
I wonder, does that also mean that for good color table modification practice, one should also always keep black as color 0?
thanks!

I think it means you should just use Coyote Graphics and never have to
worry about these kinds of things again. :-)

David
