class ColorGradient extends (Double) ⇒ Int

This class defines a color gradient that can be used for plotting colors that vary with a value. The ColorGradient is a function of Double => Int that takes the value and gives back the appropriate color. It also can be applied to a PlotDoubleSeries and it will give back a PlotIntSeries.

When you are working with Scala collections, you can use values.map(cg) to get the colors associated with the values for the data point. The second form is most useful when working with Spark. You can instead do cg('col) as the Spark Column will be implicitly converted to a PlotIntSeries and the gradient will be applied to the values.
