Peter: Thanks for making that point, which certainly did not occur to me. I see the same thing with the windows device with pointsize at the default of 12 (win.graph too). With pointsize=15 I can get two sizes smaller than the default. And on the pdf device I get many sizes less than the default. >>> Best, >>> >>> Fede >>> >>> -- >>> Federico C. F.
