Has anyone done much work with gnuplot
? I am trying to generate image maps from png/gif images generated from gnuplot. As far as I can tell, what seems to be holding me up is finding out the values (in pixels) of lmargin, rmargin, tmargin and bmargin. If I knew these I could calculate the positions of the points on my graph.
I am currently awaiting answers from their mailing list but I thought I'd ask here as well. The interface I am using to gnuplot is Chart::Graph::Gnuplot
. Thanks in advance.
