Hello Ramya,

Having many small pie slices in a scenario like yours it is hard to achieve fully readable labels. What I could suggest is try using the LabelsSettings.Distance property. In case you want to use LabelOffset you need to disable the SpiderMode as the offset won't work when SpiderModeEnabled is set to true. You could also consider using another series type to visualize the data in case the result using the above properties is not the one you have expected.

Another possible solution would be to remove the labels and show their value in the legend labels.

Hope this helps.
