onBeforeDraw in interface PlotListener

onAfterDraw

                        android.graphics.Canvas canvas)

Description copied from interface: PlotListener

Fired immediately after the Plot "source" is drawn onto canvas. Just as onBeforeDraw(...) is commonly used by Series implementations to activate a read lock, this method is commonly used to release that same lock.
