All Known Implementing Classes:

ContourPlot.DefaultColorMap, ContourPlot.SimpleColorMap

Enclosing class:

ContourPlot
```
public static interface ContourPlot.ColorMap
```
The ColorMap interface defines discrete mapping from a fixed integer interval [0..N-1] to colors through the getColor(int) method. It also defines a continuous mapping from the unit interval [0,1] to colors through the interpolate(double) method. For this each of the discrete colors is mapped to a location within the unit interval [0,1] with the first color mapping to 0 and the last mapping to 1. The colors in between have arbitrary but ascending locations within ]0,1[ which can be accessed using getLocation(int).
