Method setRangeReversed

src/qt/qcustomplot.cpp:7847–7850

! Sets whether the axis range (direction) is displayed reversed. Normally, the values on horizontal axes increase left to right, on vertical axes bottom to top. When \a reversed is set to true, the direction of increasing values is inverted. Note that the range and data interface stays the same for reversed axes, e.g. the \a lower part of the \ref setRange interface will still reference

  upper part.
