Introduction

In this article I show how to create a Pie Chart using Google Chart Tools in PHP. You can create a simple chart using Google Chart Tools. This is a very simple and provides a perfect way to visualize data on your website. The chart is exposed as JavaScript classes and all charts are populated with data using a common JavaScript data table class.  The Google Chart Tool provides many types of charts. You can easily create a chart to fit the look and feel of your site. The Google Chart Tool is a very interesting way to create a chart.

Example

<html>

  <head>

   <!--Load the AJAX API-->

   <script type="text/JavaScript" src="https://www.google.com/jsapi"></script>

   <script type="text/JavaScript">

       // Load the Visualization API and the pie chart package.

       google.load('visualization', '1.0', { 'packages': ['corechart'] });

       // Callback to run when the Google Visualization API is loaded.

       google.setOnLoadCallback(PieChart);

       // Callback that creates and populates a data table,

       // instantiates the pie chart, passes in the data and draws it.

       function PieChart() {

           // Creating the chart data.

           var data = new google.visualization.DataTable();

           data.addColumn('String', 'topping');

           data.addColumn('Number', 'slices');

           data.addRows([

                  ['Analyzer', 3],

                  ['Designer', .5],

                  ['Coder', 1],

                  ['Tester', 1],

                  ['Company', 4],

                  ['Maintenance', .5],

           ]);

           // You can set chart title and height, width

           var options = {

               'title': 'How many salaries should pay of software developers?',

               'width': 500,

               'height': 400

           };

           // Instantiate and draw our chart, passing in some options.

           var chart = new google.visualization.PieChart(document.getElementById('chart_div'));

           chart.draw(data, options);

       }

    </script>

  </head>

 <body>

    <!--Div that will hold the pie chart-->

   <div id="chart_div"></div>

 </body>

</html>

 

Output
