Method QCPAxis

3rdparty/qcustomplot/qcustomplot.cpp:8200–8267

! Constructs an Axis instance of Type \a type for the axis rect \a parent. Usually it isn't necessary to instantiate axes directly, because you can let QCustomPlot create them for you with \ref QCPAxisRect::addAxis. If you want to use own QCPAxis-subclasses however, create them manually and then inject them also via \ref QCPAxisRect::addAxis. */
