We have made a couple of minor extensions to jfreechart and are
mostly complete now with a feature to drag/drop and
cut/copy/paste XY datasets between plots and sub-plots. We
would like to contribute that (hoping it might be interesting to
others as well).
If you click in a CombinedDomainXYPlot there is a extended Menu
to cut/copy/paste Series. There is also a new Menu on a
right-click over a Legend Item to cut/copy/paste that Series.
Drag and Drop is possible between the Legend (pick a
LegendItem) and a XYPlot.
Please try it out and tell me what you think about it. These
changes are based on jfreechart-0.9.14.
