I have a pie chart in my report. I've set the Legend label format to {0} and the label format to {2}. I need the percentage to be decimal, but I don't know what I have to do?
It would be great if someone can help me.
No Chance.
Two solutions possible:
1) Create a chart customizer: http://community.jaspersoft.com/questions/539659/how-show-percentage-decimal-value-pie-chart
2) Query the percentage with the data from your datasource (or calculate in a variable), then use the label expression instead of label format
