Nikhil,

Do you have the value already in the label?
If so you you can access it like

var myval = label.getCaption().getValue();

I have create a pie chart and assigned the category definition as row["desc"] and slice size as row["value"]. Grouping is enabled on category def. and I chose Sum as the aggregate function. (See Attachment)

The legend should display desc along with the sum of values for that desc.

For example, if my data is:

Desc Value

Desc 1 5
Desc 2 4
Desc 1 7
Desc 3 3
Desc 2 6
.....

Legends should be:
Desc 1 - 12, Desc 2 - 10, Desc 3 - 3, etc.

How can I do this? I'm using scripted data set and getting an object with the above list of values.

Nikhil,

Any chance you could put dummy data in the report and post it? Then I will try to make it display correctly in the legend.
