Method cellToCoord

qcustomplot/qcustomplot.cpp:25481–25487

! Transforms cell indices given by \a keyIndex and \a valueIndex to cell indices of this QCPColorMapData instance. The resulting coordinates are returned via the output parameters \a key and \a value. If you are only interested in a key or value coordinate, you may pass 0 as \a key or \a value. \note The QCPColorMap always displays the data at equal key/value intervals, even if t
