donutjs

Simple, cross-browser (VML+SVG) donut and pie charts generator

Live demo

Usage

For CJS env the library is published as donutjs

npm install --save donutjs

const myDonutDiv = donut(options); // returns div with donut

Options

• el (Node) -- a DOM node where donut should be placed (optional)
• data (Array) -- array of objects (eg {value: 42, name: 'some name'})
• size (Number) -- diameter of the donut (100 by default)
• weight (Number) -- weight of arcs (size minus donut hole diameter) (20 by default)
• colors (Array) -- list of colors (['#555'] by default)

const myDonut = donut({
  el: document.getElementById('container'),
  size: 150,
  weight: 30,
  data: [{
    value: 1,
    name: 'A'
  },{
    value: 2,
    name: 'B',
    customData: 'Hello World'
  },{
    value: 3,
    name: 'C'
  },{
    value: 4,
    name: 'D'
  }],
  colors: ['#80a8cc', '#da3b3e', '#ffa921', 'red']
});

If options.weight === options.size/2 then you get a pie chart:

const myDonut = donut({
  el: document.getElementById('container'),
  size: 150,
  weight: 75, // <--
  ...
});

Methods

• setColor(arc, color) -- sets arc color
• data(arc[, data]) -- gets or sets data depending on second parameter existence

const arc = document.getElementById('container').querySelector('[data-name="B"]');

alert(donut.data(B_Arc).customData);

donut.setColor(arc, '#8dc700');
