Hi all, I hope you are fine. I hope you have read my first part of this series that explains about loading the Bar Chart. Today we will explain a client-side Pie Chart widget in HTML5.

Background

As you need, you need to download the files. Please download the necessary files from here.

Using the code

A simple HTML

  1. <!DOCTYPE html>  
  2. <html xmlns="http://www.w3.org/1999/xhtml">  
  3.    <head>  
  4.        <title>Pie 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.myPie = new Chart(canvasObject).Pie(pieChartData);

Here we are loading the chart in myChart.

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