Method scaleRange

tools/qcustomplot.cpp:9136–9139

! Scales the range of this axis by \a factor around the center of the current axis range. For example, if \a factor is 2.0, then the axis range will double its size, and the point at the axis range center won't have changed its position in the QCustomPlot widget (i.e. coordinates around the center will have moved symmetrically closer). If you wish to scale around a different coordinate

  overload \ref scaleRange(double factor, double center).
