I'm trying to build a structured (multiple) data graph using the PHP SVGGraph script.
I've setup my code based on what I can tell is the correct way but my graph is only outputting the age and excluding the height. Here's a screenshot showing just one column per person instead of 2.
Here is my code. Can you see anything wrong with it?
require_once('SVGGraph/SVGGraph.php');
$settings['structured_data'] = true;
$settings['structure'] = array(
'key' => 'Name',
'value' => array('Age', 'Height')
);
$graph = new SVGGraph(600, 400, $settings);
$values = array(
array('Name' => 'Bob', 'Age' => 40, 'Height' => 180),
array('Name' => 'Sam', 'Age' => 32, 'Height' => 165),
);
$graph->Values($values);
$graph->Render('BarGraph');
