So I think it's a bit too much work for the problem at hand since this API is not one of the most used API and this is likely to not impact many users. Also: * The chart module is not used anywhere else in the platform except in oldcore by the old chart plugin * I'd like use to deprecate and retire the old chart plugin Thus the chart macro and the other chart modules are good candidates to be non core extensions and thus a user who really wants to stay on the oldversion could do so (provided he doesn't use the old chart plugin). > > I am refactoring the chart macro and the interface 'ChartModel' is could > previously only be used for producing table-like datasets, but the jfree > chart library can produce plots from a wide range of dataset types.
