| Enumeration | Description |
|---|---|
| PieLabelOverlapping.Default | Show all labels including the overlapping ones. |
| PieLabelOverlapping.Hide | Hides the overlapping labels, if its content is larger than the corresponding pie segment. |
| PieLabelOverlapping.Trim | Trim overlapping data labels, if its width is larger than the corresponding pie segment. |
