Method createTickVector

3rdparty/qcustomplot/qcustomplot.cpp:6342–6354

! \internal Returns a vector containing all coordinates of ticks that should be drawn. The default implementation generates ticks with a spacing of \a tickStep (mathematically starting at the tick step origin, see \ref setTickOrigin) distributed over the passed \a range. In order for the axis ticker to generate proper sub ticks, it is necessary that the first and last tick coordina
