GetColourMap
The GetColourMap function of the AQLHistResponse class returns a dictionary used to convert numerical values into colours.
This function is generally suitable for discrete values. Additional logic will be needed to interpolate between colours on continuous values. You might want to consider GetColumnColour or GetAnalogueColourMap when working with continuous numbers.
