Method coordsToPixels

qcustomplot/qcustomplot.cpp:10913–10928

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