If PHP is OK, check out PEAR:Image_Graph http://pear.veggerby.dk/ Image examples: http://pear.veggerby.dk/samples/show/id/image_fill/ http://pear.veggerby.dk/samples/show/id/misc04/ http://pear.veggerby.dk/samples/show/id/misc05/ (2 Y-axis) http://pear.veggerby.dk/samples/show/id/multiple_plots/ http://pear.veggerby.dk/samples/show/id/plot_odo/ http://pear.veggerby.dk/samples/show/id/plot_radar/ http://pear.veggerby.dk/samples/show/id/plot_radar_smooth/ Alpha blending is implicit in GD though (inside the color information), so you should be able to use it. See http://search.cpan.org/dist/GD/GD.pm (colorAllocateAlpha(), saveAlpha(1), alphaBlending(0), PNG). The set_clr() of GD::Graph could easily be enhanced. But PEAR::Image_Graph already has all that, and much more. -- Affijn, Ruud "Gewoon is een tijger." -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
