Would be nice if David would reply :)

I think it would be very good for lazarus to have a good Tee-Chart
compatible graphing component. The easiest way would be for Steema to
publish a GPL version of and old version of Tee-chart.
I believe that releasing the source with GPL license for such an old
version wouldn't be a problem. But that's their choice.
Maybe the community could buy the source (like the blender people).
