===GetAnalogueColourMap===

The **GetAnalogueColourMap** function of the [[mplreport]] class returns a colour map that allows you to convert the analogue value of a property to a matching colour using the [[AQLHistResponse]] object returned from the [[FetchHistory]] command.

This is usually used to create heatmaps or other colour-coded displays of analogue values. If colouring //discrete// values, use [[GetDiscreteColourMap]].

==Parameters==

^Parameter^Type^Default^Meaning^
|dta|AQLHistResponse||The AQL query response, usually from [[FetchHistory]].|
|col|str||The name of the column you want to build a colour map for|

==Return==

This function returns a tuple with three components.

The first is the colour map itself, a MatPlotLib **LinearSegmentedColourMap** object.

The second and third are the //minimum// and //maximum// (respectively) values that the colour map represents, which should also be the min and max vales of the property itself.
