Postscript to the discussion of "missing pixels" in some titles and/or labels in on-screen graphs: I believe this is now fixed. Ethan Merritt (gnuplot developer) and I figured out a workaround for the incorrect rendering of fonts in PNG graphs on Windows. The fix is in the current gretl snapshot for Windows and will shortly be in gnuplot CVS. I've also updated the gnuplot help file for Windows so that it includes help for the pngcairo and pdfcairo "terminals". Allin Cottrell
