Method setDataRange

src/qt/qcustomplot.cpp:19450–19459

! Sets the range spanned by the color gradient and that is shown by the axis in the color scale. It is equivalent to calling QCPColorMap::setDataRange on any of the connected color maps. It is also equivalent to directly accessing the \ref axis and setting its range with \ref QCPAxis::setRange. \see setDataScaleType, setGradient, rescaleDataRange */
