it is along time (almost 3 years) I do not work with graphs and chart
but I was always fashinated by them.
I'm sorry but right now I cannot help you much on improving KPlotW, but

I'm sure you have plenty of ideas on what to add to KPlotW but, IMHO,
the first think you may take a look for "stealing" some ideas/design is

The best way to understand it, is to see it in action: download tcl/tk
and blt and run the examples.
Hope this will be useful
