Hello. I have been using Matlab and Excel to plot graphs for academic papers. While both are good applications for plotting simple graphs with 3 or less curves in each graph, I run out of line styles and color when I try to plot many curves on the same graph. The situation is worsen when it is required that all the curves be in black and white. Do you know of good applications (freeware and commercial) that allow can provide nice looking graphs with lots of choices of line styles? Thanks.
