Hi,

You have to read the whole article to avoid this error. (Don't you hate
it when this happens - I'll bet you read the rest of the article just
after hitting the send button. I do that waaay too often. Ready! Fire!
Aim!)

It's objects all the way down. By not specifying the font you accepted
the the default - to do the symbol stuff you need more vectory fonts
like Hershey (which is the default for Direct Graphics.)

xobjview,obj_new('IDLgrText',Enable_Formatting=1,"!Z('03B5'x) ", $
font = obj_new('IDLgrFont', 'Hershey'))

If you are digging to OG I recommend Ronn Kling's "Power Graphics with
IDL". www.rlkling.com

Cheers,
Ben
