Method setScaleType

qcustomplot.cpp:7674–7684

! Sets whether the axis uses a linear scale or a logarithmic scale. Note that this method controls the coordinate transformation. For logarithmic scales, you will likely also want to use a logarithmic tick spacing and labeling, which can be achieved by setting the axis ticker to an instance of \ref QCPAxisTickerLog : \snippet documentation/doc-code-snippets/mainwindow.cpp qcpaxisti
