```
public class InterpolateColourScheme
extends EnumeratedColourScheme
```
Takes a list of interpolation points with colours and data points. If a data value is below the first point then the first colour is returned. If it is above the last point then the last colour is returned. If it is in between two points then the colour is interpolated. This provides the functionality required by the Symbology Encoding interpolation function.
