Method setSelectionDecorator

qcustomplot/qcustomplot.cpp:10860–10875

! Use this method to set an own QCPSelectionDecorator (subclass) instance. This allows you to customize the visual representation of selected data ranges further than by using the default QCPSelectionDecorator. The plottable takes ownership of the \a decorator. The currently set decorator can be accessed via \ref selectionDecorator. */

  The currently set decorator can be accessed via \ref selectionDecorator.
