Constructor Detail

SimpleColorMap

public SimpleColorMap(int[] colors,
                      double[] locations)

Creates a ContourPlot.SimpleColorMap with the specified colors and corresponding locations in the unit interval. As required by the ContourPlot.ColorMap interface the first location has to be 0, the last location has to 1 and the locations in between have to monotonically increase within ]0,1[.

Parameters:

colors - integer packed ARGB values (e.g. 0xff00ff00 is opaque green)

locations - corresponding to colors. Within [0,1].

Throws:

java.lang.IllegalArgumentException - if colors and locations are of different lengths, if less than 2 colors are specified, if locations does not start with 0 or does not end with 1, if locations is not sorted in ascending order.

SimpleColorMap

public SimpleColorMap(int... colors)

Creates a new ContourPlot.SimpleColorMap with the specified colors and uniform spacing.

Parameters:

colors - integer packed ARGB values (e.g. 0xff00ff00 is opaque green)

Throws:

java.lang.IllegalArgumentException - when less than 2 colors are specified.

getLocation

public double getLocation(int index)

Description copied from interface: ContourPlot.ColorMap

Returns the location of the ith color within the unit interval.

Specified by:

getLocation in interface ContourPlot.ColorMap

Parameters:

index - index of the location/color

Returns:

location within [0,1]

getLocations

public double[] getLocations()

Specified by:

getLocations in interface ContourPlot.ColorMap

Returns:

all locations of the discrete colors in this ContourPlot.ColorMap
