<?php

include_once '/Libraries/PHP/OpenFlashChart/php-ofc-library/open-flash-chart.php';
$title = new title( date("D M d Y") );

$bar = new bar();
$bar->set_values( array(9,8,7,6,5,4,3,2,1) );
$bar->set_colour( '#94D700' );

$chart_1 = new open_flash_chart();
$chart_1->set_title( $title );
$chart_1->add_element( $bar );
//
//
$data_1 = $chart_1->toPrettyString();
//
//

//
// CHART 2
//
// generate some random data
srand((double)microtime()*1000000);

$tmp = array();
for( $i=0; $i<9; $i++ )
$tmp[] = rand(1,10);

$bar_2 = new bar();
$bar_2->set_values( $tmp );

$chart_2 = new open_flash_chart();
$chart_2->set_title( new title( "Chart 2 :-)" ) );
$chart_2->add_element( $bar_2 );
//

$data_2 = $chart_2->toPrettyString();

var data_2 = $data_2;

<div id="div_chart_1"></div>
<div id="div_chart_2"></div>

Granted this is the sample code from the openflashchart website.. Once I get this working I can work my own data into it.. At the moment with I run this, the following error comes up ;

Open Flash Chart
IO ERROR
Loading test data
Error #2032

This is the URL that I tried to open:../../data-files/y-axis-auto-st

Open Flash Chart
IO ERROR

Error #2032

This is the URL that I tried to open:../../data-files/y-axis-auto-steps.txt

Ive trying to get this working for a couple of days now with no joy.. Thanks for the reply, help will be extremely appreciated..

Is this directory outside the web space area (outside DOCUMENT_ROOT)?
If so, it might be blocked by php's security settings.
Try putting the file beside the php script to see if it works.

Thanks for the reply, i might have misunderstood your advice, but what i did was copy the y-axis-auto-steps.txt into my htdocs folder (where my php file is located). Two graphs appeared but there were the same graph and not the graph that i coded.. It appears to have graphed a default one.. Have u ever come across that before??

Thanks

Yup, that is what I meant. It does sound like some progress.
I don't know OpenFlashCharts at all so I only have general debugging strategies.

Do you have any example code you could try? If that works then it might imply that your data file is corrupt.
