Method layerableListAt

qcustomplot.cpp:15594–15615

! \internal Returns the layerables at pixel position \a pos. If \a onlySelectable is set to true, only those layerables that are selectable will be considered. (Layerable subclasses communicate their selectability via the QCPLayerable::selectTest method, by returning -1.) The returned list is sorted by the layerable/drawing order. If you only need to know the top-most layerable, rather
