Thank you, thank you. This is an excellent post. I had no idea about AttrPriority=Color. Just yesterday I was working on a bunch of quick plots which should use color only to distinguish groups, but since I was being lazy I didn't bother to force the line styles and symbols to be the same. Looks like all I'll need to do is set that one option to get the graphs I want. Glad I started my day by reading your blog!
