Hi there!
This is one of those "more annoying than it should be things" in Excel.
- Delete the chart and create a new one by selecting cells A2:C10 and clicking Pie on the Insert tab.
- Right-click over the pie chart pieces and click Format Data Series...
- In the Series Options section click the option for "Secondary Axis" and hit OK.
- Go to the Layout tab and select Series 1 from the drop-down menu in the upper left of the ribbon menu.
- Click the Data Labels button and click Outside End.
- Repeat the last two steps for Series 2 but select Inside End this time.
I hope this can help you!
