//////////////////////

​

// Deliberately vague to be general enough to allow for many different types

// of data, but is it too vague to be useful?  Since the interface is meant

// to be a simple plotter, it may be better to restrict PlotData to be more

// like PlotPointData, which would eliminate possibilities for data like

// functions but would also eliminate a lot of vaguery.

    // Returns whether the contained data is valid or not.
