Method axisRectAt

3rdparty/qcustomplot/qcustomplot.cpp:14994–15015

! Returns the layout element of type \ref QCPAxisRect at pixel position \a pos. This method ignores other layout elements even if they are visually in front of the axis rect (e.g. a \ref QCPLegend). If there is no axis rect at that position, returns \c nullptr. Only visible axis rects are used. If \ref QCPLayoutElement::setVisible on the axis rect itself or on any of its parent elements
