Pie Chart By Google Chart Tools in PHP

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 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);

}
