Method pixelsToCoords

3rdparty/qcustomplot/qcustomplot.cpp:11671–11686

! Convenience function for transforming a x/y pixel pair on the QCustomPlot surface to plot coordinates, taking the orientations of the axes associated with this plottable into account (e.g. whether key represents x or y). \a x and \a y are transformed to the plot coodinates and are written to \a key and \a value. \see coordsToPixels, QCPAxis::coordToPixel */
