GetDiscreteColourMap
The GetDiscreteColourMap function of the mplreport class returns a lookup array of the possible values of a discrete property and the associated MatPlotLib RGB colours for those values, based on an AQLHistResponse object.
This is usually used to create heatmaps, status-lines, broken bar-charts or other colour-coded displays of discrete values. If colouring continuous values, use GetAnalogueColourMap.
Reports using this function may also want to use GetDiscreteLegend.
