Constructor Detail

ContinousColorMap

public ContinousColorMap(double maxvalue,
                         double minvalue,
                         ColorScale cs)

Generate a continous color map based on a color scale and a minimal and maximal value.

Parameters:

maxvalue - the maximum value this map shall be able to map

minvalue - the minimum this map shall be able to map

cs - the colorscale this map should use for color generation.

Method Detail

resetColorData

protected void resetColorData()

Clear all color related data i.e. ColorScale Colors, fRactions and Panes.

setup

protected void setup()

Setup this Color Map.

buildColorMapVisualisation

protected JComponent buildColorMapVisualisation(HashMap<Double,String> translate,
                                                JScrollPane Legend)

Generate the Color Scale Layout and visual representation based on the Labels used for the respective positions.

Parameters:

translate - A Translation between the double values and Strings.

Legend - The Legend to build this ColorMap Visualisation for (to listen to resize events).

Returns:

A JComponent which plots the ColorMap

getCenterValue

protected double getCenterValue()

Get the center value (i.e. the value in the middle between the minimum and maximum values mapped by this map.

Returns:

the center value

GetLabelForNumbers

protected HashMap<Double,String> GetLabelForNumbers(HashMap<Double,Double> fractions)

Create Strings Representations for the values in a Map which are Doubles. This is a helper function to allow the generation of sensible numbers for legends.

Parameters:

fractions - A Translation between double keys to double values. The values will be used to generate strings.

Returns:

a Map, that maps the keys of the input to the string representation of the values of the input.

getColor

public Color getColor(Comparable Value)

Description copied from class: ColorMap

Get the Color that is associated with the Comparable object provided.

Specified by:

getColor in class ColorMap

Parameters:

Value - A Comparable value.

Returns:

a Color

getCenterPosition

public double getCenterPosition()

Get the central position of the color map (on a 0-1 range). This is the position that returns the value of the ColorScale when 0.5 is requested from a basic colorscale used for this map.

Returns:

the central position of the ColorMap
