I'm using IDL 5.0.2 on a Win98 platform. My graphics adapter is running
in 16-bit (65536 color) mode. Despite much experimentation and perusal
of Dave Fanning's excellent web site, I cannot get the colors to come
out correctly. I have set decomposed=0 and loaded the rainbow color
table (#13). If I plot data points with the plots command and a color
index array, the colors still come out in a black to red continuum, but
if I issue a command like
tv,congrid(indgen(16,16),160,160)
I see that the colors work as expected for the tv command. I get an
image showing the rainbow spectrum of colors, as I would like for plots
commands. How can I make the plots command honor the color table?
