[Solved] Pie Chart Label Problem

[Barry]

The chart below only shows the 'Key' value in the Labels.

What modifications are required to show the 'Key' and the 'Value' in the labels.

Thank you, Barry

Hi Barry,

Thanks for contacting us.
You may use the ItemLabelFormat property of the series and set as many properties of your business object as you want to be visualized in a single label.
For the purpose you should use a #DATAITEM token. More about it, as well as code samples can be found in our documentation.

Kind regards,
Evgenia
