Template:Graph:PieChart

Template documentation[view] [edit] [history] [purge]

Pie charts edit

You can add a pie chart with a call to this template. This template uses the Vega version 2 JSON specification. An older template {{Pie chart}} is based on CSS rendering. The template GraphChart allows adding of map, line, bar and area charts, as well as stacked line, stacked bar and stacked area charts, but no pie charts. The template GraphChart also uses Vega version 2 and uses Module:Graph with Scribunto/Lua programming. This Template:Graph:PieChart doesn't use Lua.

Parameters edit

radius specifies the radius of the pie chart in pixels, default is 100
legend specifies the title to be displayed above the legend, default is "Legend". To hide legend, set it to a "-" value without quotes.
values this is a list between square brackets of comma separated label value pairs between single curly braces like [ {"x": "Peaches","y": 100}, {"x": "Plums","y": 32}]
rangeliteral this can be one of the Vega specified rangeliterals, default is "category10", but can also be a list like ["red", "green"]

Examples edit

Example usage:

{{Graph:PieChart|legend=Fruits|radius=125|values= [
      {"x": "Peaches","y": 100},
      {"x": "Plums","y": 32},
