Mapper

__init__ ( self,  plotView )

This constructor does little more than call IPlotView's constructor

clearColors ( self )

clearColors(self)

clear set plot coloring.

getPlotColors ( self )

getPlotColors(self)

An implimentation of the only required colorMapper class.

setColorByColValue (
        self,
        col,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

setHueByColValue(self,col, hRange(0,1))

sets the color to be a function of the value for that row at a given column.

setColorByFunction (
        self,
        function,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

setColorByFunction(self, funct, component=h, minValue, maxValue, colorRange(0,.7))

function should take in a dataset and a row and return a single float. Colors will be scaled based on that value.

function prototype should be:

value = function(dataset, row)

setColorByIndex (
        self,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

setColorByFunction(self, funct)

your function needs to return a valid HSV tuple for each row of the dataset, given the dataset. ie.

[listOfColorTuples] = function(ds)

setColorByLabeling (
        self,
        labeling,
        labels=None,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

setColorByLabeling(self, labeling=None, component=h, minValue=None, maxValue=None, colorRange(0,.7))

uses the labeling to produces a color list for plotting. If the labeling contains real values, then the optional parameters minValue and maxValue can be used to scale the colorRange used. Only uses the first label attached to every row

setColorByLabelingCounts (
        self,
        labeling,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

sets the given color component's value proportional to the size of the class

setColorByTupleLabeling (
        self,
        labeling,
        element=0,
        component='h',
        minValue=None,
        maxValue=None,
        colorRange=( 0,.7 ),
        )

setColorByTupleLabeling(self, labeling=None, component=h, minValue=None, maxValue=None, colorRange(0,.7))

uses the labeling to produces a color list for plotting. If the labeling contains real values, then the optional parameters minValue and maxValue can be used to scale the colorRange used. Only uses the first label attached to every row

setColors ( self,  list )

setColors(self, list)

This takes in a list of HSV tuples and sets them to be the colors for plotting.
