<?php
  include( 'chartlogix.inc.php' );

  $pie = new PieChart();

  $pie->setTitle( "ChartLogix Pie Chart" );

  $pie->addData( 'Bananas', 420, 'FFCC00' );
  $pie->addData( 'Apples', 400, '99FF00' );
  $pie->addData( 'Strawberries', 210, 'FF6666' );
  $pie->addData( 'Grapes', 350, '009900' );
  $pie->addData( 'Plums', 100, '9900CC' );
  $pie->addData( 'Others', 190, 'AAAAAA' );

  $pie->drawPNG( 500, 400 );

Then put an img tag in your HTML refering to the graph script:

Line-by-line

First, you need to include the ChartLogix PHP file:

include( 'chartlogix.inc.php' );

Then create a new PieChart object:

$pie = new PieChart();

If you want the pie chart image to contain a title you can add it using the setTitle function:

$pie->setTitle( 'This is a pie chart' );

To add values to the pie chart use the addData function:

$pie->addData( 'A Pie Slice', 25, 'FFFF00' );

This adds a yellow pie slice, with a value of 25. Colours are specified as hexadecimal HTML colours.

Once you have added all your data, the final step is to output an image to the Web browser:

$pie->drawPNG( 500, 400 );

You specify the width and height in pixels. The drawPNG function sets the correct Content-type in the HTTP header and outputs the image data.

To display a CubeLogix pie chart in the web browser, you would use an img tag, and point it's src at the PHP script which creates the pie chart:

The Examples Page contains some complete PHP scripts which generate pie charts.

The Function Reference Page gives you a complete list of functions which you can use to customise the deisgn of the pie chart.

The Pie Chart Designer allows you to interactively customise a pie chart and see the PHP code.
