React Circular Multi Progressbar

This is a fork of Kevin Qi's react-circular-progressbar that adds support for multiple bars within a single progressbar ring.

Multibar usage

<CircularProgressbar percentage={0} stackPercentages={[10, 20, 70]} />

Original README follows

A circular progress indicator component, built with SVG. Easily customizable with CSS. See a live demo.

Installation

Install the npm module:

npm install react-circular-progressbar

Important: you'll also need to copy src/styles.css into your repo to use the default styling!

Usage

Import the component:

import CircularProgressbar from 'react-circular-progressbar';

..and use the component in your JSX:

<CircularProgressbar percentage={60} />

For more in-depth examples, take a look at the demo code to see JSX for the live demo page.

Props

Name	Description
`percentage`	Numeric percentage to display, from 0-100. Required.
`className`	Classes to apply to the svg element
`strokeWidth`	Width of circular line as a percentage relative to total width of component. Default: `8`.
`background`	Whether to display background color. Default: `false`.
`backgroundPadding`	Padding between background and edge of svg as a percentage relative to total width of component. Default: `0`.
`initialAnimation`	Toggle whether to animate progress starting from 0% on initial mount. Default: `false`.
`counterClockwise`	Toggle whether to rotate progressbar in counterclockwise direction. Default: `false`.
`classForPercentage`	Function which returns an additional class to apply to top-level svg element, which can be used for coloring/styling percentage ranges differently. Example: `(percent) => percent < 100 ? 'incomplete' : 'complete'`.
`textForPercentage`	Function which returns text to display, can be configured based on percentage. Example: (pct) => `${pct}%`.
`classes`	Object mapping to override classNames of each svg element (root, trail, path, text, background). Enables styling with react-jss. See this PR for more detail.

Customizing styles

Use plain CSS to customize the styling - the default CSS is a good starting point, but you can modify it as needed.

CSS hooks

There are CSS hooks for the path, trail, text, and background of the progressbar which you can customize, e.g.:

.CircularProgressbar-path       { stroke: red; }
.CircularProgressbar-trail      { stroke: gray; }
.CircularProgressbar-text       { fill: yellow; }
.CircularProgressbar-background { fill: green; }

Using multiple themes

You can use the className prop to add different classes to the top-level SVG element, and then use that to add different themes to different instances, e.g.:

<CircularProgressbar percentage={25} className="progressbar-red" />
<CircularProgressbar percentage={25} className="progressbar-blue" />

.progressbar-red .CircularProgressbar-path { stroke: red; }
.progressbar-blue .CircularProgressbar-path { stroke: blue; }

Advanced usage

A lot of use cases can be covered with CSS. A few examples:
