 use of {x} as index to array inside setAggregateLabelFormat |

Hi,
assuming that I have defined an array of integers called $data4[], can I used the {value} or {x} fields as indexes into that array while using setAggregateLabelFormat for a stack-bar chart?
Something like this?
$layer->setAggregateLabelFormat("{=$data4[={x}] }");
I've tried numerous permutations but can't quite find the correct syntax.
Thanks!

Hi Richard,
For your case, the following are some options:
(a) You can just tell ChartDirector what label you want to display on each stacked bar by adding $data as an extra field:
$layer->addExtraField($data4);
// Use the extra field as the aggregate label
$layer->setAggregateLabelFormat("{field0}");
(b) You can use Layer.addCustomAggregateLabel in a loop to specify the labels.
