Info before start

For this type of chart you need only osY values in fact. They must be positive to show on chart. The osX is taken as labels here (can be strings). Colors are calculated according to the osY length, more data more colors.

Usage - show

<html>
  <head>
    <meta charset="UTF-8" />
    <title>example</title>
    <style>
    .ChartPie {
      width: 800px;
      border: 1px solid red;
    }
    </style>
  </head>
  <body>
    <div id="app"></div>
    <script src="index.js"></script>

var chart = { msg: "test chart", osX: [], osY: [] };
for (var i=0,x=0; i<5; i++,x++) {
  chart.osX[i] = "id "+x;
  chart.osY[i] = x+5;
}

ReactDOM.render(
  <rcl.ChartPie data={chart}/>,
  document.getElementById('app')
);

Usage - update

index.js

function setRandomChart() {
  var chart = { msg: "testing random chart", osX: [], osY: [] };
  for (var i=0,x=0; i<8; i++,x++) {
    chart.osX[i] = "id "+x;
    chart.osY[i] = x*Math.random();
  }
  ReactDOM.render(
    <rcl.ChartPie data={chart}/>,
    document.getElementById('app')
  );
}
setInterval(() => { setRandomChart() }, 5000);

Demo

The demo is available in module directory. To test the demo just go to demo directory in module folder and open index.html in your browser.

However, you can build the demo again with npm. To re-build the demo just go to demo directory in module folder and run command:

npm run build

This should download all packages and build the demo index.js file again. After it, you can open index.html in your browser. Should work :-)
