Javascript Pie Chart php to javascript object array

Question

I am using the code at http://jsfiddle.net/MX7JC/9/ to build a pie chart.

But I want the data to come from php variables. How do I change :

var agg = { label: 'Aggressive', pct: [60, 10, 6, 30, 14, 10] },

as seen in the code on the link, so that pct consists of an array of php variables rather than fixed numbers. Such as :

var agg = { label: 'Aggressive', pct: [$r1, $r2, $r3, $r4, $r5, $r6]},

How do I alter the code to allows this? I tried json encode and I am having problems.

You can generate the Javascript when it's defined using PHP:

<script type="text/javascript">
    var agg = { label: 'Aggressive', pct: [
        <?php echo $r1.", ".$r2.", ".$r3.", ".$r4.", ".$r5.", ".$r6; ?>
    ]},
</script>
