Color Maps

The <color-map> setting allows you to map input data to colors. These are the currently implemented mapping methods:


;; a 'step' color map
(steps (<step> <color>)...)

;; a 'gradient' color map
(gradient (<step> <color>)...)


Below you can see simple scatter plot that uses a red to blue color map to display a third data dimension. The full source for this example is at: examples/charts-scientific/scatterplot_colors


The color map specification used in the example is:

;; gradient from gray to black
color-map (gradient (0 #aaa) (1.0 #000))
