Method minimumSizeHint

qcustomplot/qcustomplot.cpp:14725–14728

! \internal Returns a minimum size hint that corresponds to the minimum size of the top level layout (\ref plotLayout). To prevent QCustomPlot from being collapsed to size/width zero, set a minimum size (setMinimumSize) either on the whole QCustomPlot or on any layout elements inside the plot. This is especially important, when placed in a QLayout where other components try to take in a

  much space as possible (e.g. QMdiArea).
