## 7.5. Additional color handling

Some plot types have additional color handling to facilitate easier handling and differentiation between data sets.

Pie plots

  Pie plots support the concept of color-themes. A color theme is simple a set of colors used for consecutive slices within the Pie. How to specify color-themes is further discussed in Section 16.1.9.

Color maps

  Matrix (Only available in the Pro-version) and contour plots also have the concept of color maps. This is a range of colors used to indicate the data in the plot. Examples of color maps can be found in Section 22.8. (Color maps are defined and implemented in "`jpgraph_colormap.inc.php`").
