Getting Rid of Red Plots in IDL
If you'd like to get rid of red backgrounds in plot windows in IDL and have white backgrounds instead, type the following at the command line before you type your plot statement:
device, true=24, retain=2, decomposed=0
And then try plotting something:
plot, sin(2*!pi*findgen(50)/50.), background=255, color=0
If you don't want to type this every time, put this line in your IDL_STARTUP file as I described above. My IDL startup file is called .idl_startup.pro where I put the dot out front so I don't have to see it every time I open my home directory in Finder.
