Open Flash Chart

:: Home - Gallery - Scatter Chart

Info: Open Flash Chart 2 is out. Version 1.x and these pages will never disappear and the charts will continue working forever, but further development on 1.x has stopped. Take a look at version 2 here Open Flash Chart 2.

Gallery - Scatter Chart

You can mix scatter charts with line charts. You can also plot points at any real position, e.g. at 0.5, 0.5

Adding lines in is a little clinky, but it works.

Create the flash object

<?php
include_once 'ofc-library/open_flash_chart_object.php';
open_flash_chart_object( 500, 300, 'http://'. $_SERVER['SERVER_NAME'] .'/open-flash-chart/gallery-data-50.php' );
?>

gallery-data-50.php

<?php
include_once( 'ofc-library/open-flash-chart.php' );

$a = array();
$b = array();
$c = array();

$a[] = new point(-0.5,-0.5,5);
$a[] = new point(0.5,0.5,5);
$a[] = new point(0,0,5);

$b[] = new point(-3,3,5);

$tmp = -4;
for( $i=-5; $i<6; $i++ )
{
    $c[] = $tmp;
    $tmp += 0.2;
}
