At least it is until you send the contents of that
draw widget off to a PostScript file. Then you will
be back. Here is a hint: white on white. :-)

Cheers,

I always use the latest. Andrew is always 4-5 years
behind on government VAX computers. :-)

Hey David,

I dont know which version of IDL u use but in 6.2 this is the result:
Erase, Color=FSC_Color('sky blue')
% Variable is undefined: FSC_COLOR.

Andrew Cool writes:
!P.background = 255
erase
!P.Color = 0

This is a good solution.

Thanks !

David,

I didn't want to tread on the chance for you to sell another book! ;-)
