All you have to do is add a 'Chart' field in the report and set the Chart's DataX and DataY properties to the values you want to display on the chart. Then you need to change the 'LabelAutoArrangeOptions' and 'LabelCompass' properties from 'None' to a desired value. The labels will automatically be added in the charts depicting the values in the chart. The labels can also be customized by setting other properties like: 'LabelConnected,' 'LabelAutoArrangeMethod' and 'LabelOffset.' _ Note: When using Pie Charts, you need to set the 'RadialLabels' property to 'True.'_ You can Download the report xml that shows the implementation of the labels with the following properties: LabelAutoArrangeMethod : Decimation LabelAutoArrangeOptions : Top LabelCompass : Auto LabelConnected : True LabelOffset : 20 RadialLabels : False And the following would be the output generated:
