d3-rs-radial-chart is a component for creating a customizable radial chart for your application, e.g. to show data over time like monthly expenses on taxis over a year. It is provided as a custom element for easy integration into your projects.
If your browser does NOT support custom elements natively (see caniuse) you have to install the web components shim and include it in your project before including this component!
The component is part of the RedsiftUI library. For a documentation of the hero unit see the official RedsiftUI documentation.
A UMD build is available from //static.redsift.io/reusable/d3-rs-radial-chart/latest/d3-rs-radial-chart.umd-es2015.min.js.
To build locally checkout this repository and
> cd d3-rs-radial-chart
> npm install
> npm run buildThis will create a ./dist folder with the Javascript and CSS files.
First include the CSS file in the <head> of your page:
<link rel="stylesheet" href="//static.redsift.io/reusable/d3-rs-radial-chart/latest/css/d3-rs-radial-chart.min.css">Additionally include the Javascript on the bottom of the <body>:
<script src="//d3js.org/d3.v3.min.js"></script>
<script src="//static.redsift.io/reusable/d3-rs-radial-chart/latest/js/d3-rs-radial-chart.umd-es2015.min.js"></script>Including the Javascript already registers the custom element rs-radial-chart with the browser. Make sure to include D3 before the component, as it depends on it!
Use the following HTML code to create a rs-radial-chart element:
<rs-radial-chart></rs-radial-chart>You can optionally provide a DIV with the ID chart like so:
<rs-radial-chart>
<div id="chart"></div>
</rs-radial-chart>If provided the chart will render into this DIV, giving you more control over e.g. styling. If not provided a DIV is created automatically by the element.
Data is added to the chart via Javascript in the following form:
var chart = document.querySelector('rs-radial-chart');
var data = [{
name: "Jan",
value: 3.6732592034888905,
color: () => { return '#00ff00'; }

chart.data = data;If your browser does not support custom elements (and only then!) make sure to wrap the above code into the following code:
window.addEventListener('WebComponentsReady', function(e) {
// setup code ...
});See a description of why this is necessary here.
