Provides appropriate (not too long) representations of the values provided. The input values have to be ordered from smallest to largest and it is assumed, that values[0] is the minimum and values[last] is the largest value.

Parameters:

values - The double values for which to generate Display strings.

Returns:

A map matching Strings to the provided Double values.

getDefaultColor

public Color getDefaultColor()

getColorScalePane

public ColorScalePane getColorScalePane()

Get a visual representation of the ColorScale used in this map. This is in fact, the ColorScalePane produced by the enclosed ColorScale

Returns:

a ColorScalePane that can be displayed.

setColorScale

public abstract void setColorScale(ColorScale scale)

Set a specific ColorScale to be used by this ColorMap. The Colormap will be reset to use the provided ColorScale.

Parameters:

scale - the ColorScale to be used.

getColorMapComponent

public abstract JComponent getColorMapComponent(JScrollPane Legend)

Get a Component that represents this ColorMap

Parameters:

Legend - The legend this component is part of (to obtain resize events).

Returns:

A JComponent that plots information about this ColorMap
