You can try to enable spider mode (demonstrated here
) but still, results cannot be guaranteed for all the cases. We appreciate your feedback on the automatic aggregation, but currently you will need to do this manually. That is, you can analyze the data, combine the last 10% in a single item and set up another pie, which shows the distribution amongst these smallest items.
Alternatively, let me get back to Sia's suggestion for placing those labels in the legend. I do find it viable as the pie slices for the smallest items are barely visible anyways and the information about these items is mainly displayed by the labels i.e. it is just text. Putting it in the legend will guarantee you ordered display with no overlaps.
