public class ColorFeatureGradiated

extends ColorFeatureConcrete

A class for displaying a gradiated color whose intensity is determined by the supplied UnitIntervalDataPoint. The data point is bracketed, so values outside of the range 0.0 - 1.0 will be treeated as minimum and maximum respectivly.

Since:

1.0

Version:

1.2
