Can we have a data set column as label for value series in a pie chart. Suppose my PL/SQL proc returns three columns as "Name", "Count_1" and "Count_2" and I set the pie slice size to be defined by Count_1. So the labels of pie slices will by default be Count_1 values. Now I want the label of pie slices be <Count_1 (Count_2)>. How can this be done?

One way to do this is to load up a global variable from a hidden table
and then reference it in chart script. Look at the attached example.
Specifically the oncreate for the table detail row and the
beforeDrawDataPointLabel script on the chart.

Thanks Jason. It works well.

But I guess this could be a new feature wherein labels can be bound to data set rows so that workarounds are not needed. I mean if I can have data set bounding for mouseover action then surely I should be allowed to add it to labels.

Agreed. I looked through bugzilla on this one and found:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=158875

This was marked as a duplicate, but the duplicate bug was marked as
fixed, which was only a partial fix. Can you open another bugzilla
entry for this one?
