This template uses Lua:

Module:ChartColors (sandbox)

This template displays standard color palettes: Category20 and Plotter. These color palettes can be used for statistical diagrams.

To translate or review the translation of the module to your language, edit carefully Data:I18n/ChartColors.tab.

Syntax

{{ChartColors|color palette|number of colors|show the color number}}

Full color of diagram palettes. Moving the mouse cursor over each box the color number appears.

Palette	Code	Note
Category20 (When n > 10)	`{{ChartColors\|Categ20\|20}}`	Normal order
	`{{ChartColors\|Categ20_3\|20}}`	The first color is the 3rd
	`{{ChartColors\|Categ20_i_3\|20}}`	Inverted order
Category10 (Categ20 in the code. When n < 11)	`{{ChartColors\|Categ20\|10}}`	Normal order (1st, 3rd, 5th, ... of Category20)
	`{{ChartColors\|Categ20_2\|10}}`	The first color is the 2nd (of Category20)
	`{{ChartColors\|Categ20_3\|10}}`	The first color is the 3rd (of Category20)
	`{{ChartColors\|Categ20_i\|10}}`	Inverted order
Plotter	`{{ChartColors\|Plotter\|26}}`	Normal order
Plotter	`{{ChartColors\|Plotter_i\|26}}`	Inverted order

The number of colors must be from 1 to 20 (Categ20) or 26 (Plotter).

Show the color number is an optional parameter, with two values: '-' the color number and 'a' with the degree of transparency (alpha channel) added at the end of the number and always it will be 'ff'. It is only interesting to add the color for the map coloring.
