I hope you have read my first two articles in this series that explains the loading of a Bar Chart, Pie Chart and Doughnut Chart. Please see the following links.

Now we will explain a client-side Doughnut Chart widget in HTML5.

Background

Please download the necessary files here http://www.chartjs.org/.

Using the code

A simple HTML

  1. <!DOCTYPE html>
  2. <html xmlns=“http://www.w3.org/1999/xhtml”>
  3.    <head>
  4.        <title> Polar Area Chart Using Chart.js</title>
  5.    </head>
  6.    <body></body>
  7. </html>

Included JavaScript file

  1. <script src=“Chart.js”></script>

Call the Chart Function

  1. window.onload = function () {
  2.             var canvasObject = document.getElementById(“myChart”).getContext(“2d”);
  3.             window.myPolarArea = new Chart(canvasObject).PolarArea(polarChartData, {
  4.                 responsive: true
  5.             });
  6.         }

Here we are loading the chart in the myChart.

As you can see in the preceding code, polarChartData is the data we will load into the chart.

  1. var polarChartData = [
  2.     {
  3.         value: 200,
  4.         color: “#F7464A”,
  5.         highlight: “#FF5A5E”,
  6.         label: “Monday”
  7.     },
  8.     {
  9.         value: 50,
  10.         color: “#46BFBD”,
  11.         highlight: “#5AD3D1”,
  12.         label: “Tuesday”
  13.     },
  14.     {
  15.         value: 150,
  16.         color: “#FDB45C”,
  17.         highlight: “#FFC870”,
  18.         label: “Wednesday”
  19.     },
  20.     {
  21.         value: 20,
  22.         color: “#949FB1”,
  23.         highlight: “#A8B3C5”,
  24.         label: “Saturday”
  25.     },
  26.     {
  27.         value: 400,
  28.         color: “#4D5360”,
  29.         highlight: “#616774”,
  30.         label: “Sunday”
  31.     }
  33.                  ];
