It's not that it can't be done, it's just that IMHO there's a much better tool for the job already. But if somebody comes with a set of math symbols, I'd be happy to put them in. > I frequently use graphics to help sort out data I acquire.

There are other, more pressing, fronts for me ATM, such as the text handling (which sucks, I hear:). -Lars _______________________________________________ Dia-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/dia-list FAQ at http://www.gnome.org/projects/dia/faq.html Main page at http://www.gnome.org/projects/dia
