statistics: don't replot chart when changing features

Browse source 
Up to now, when the user changed the visibility of chart features
(legend, quartiles, labels, etc.) the whole chart was replot.
Instead, only change the visibility status of these items.

After all, this modularity is one of the things the conversion
to QSG was all about.
