under the standard moods pie chart, the list of all moods is displayed, ordered by the most frequent to the last frequent, and you can select them to hide or display them.

It would be nice to have the same thing under custom pie charts, possibly with a toggle to add it or not, because in pie charts with a lot of values it becomes impossible to read or select them.

For example I have the attached pie chart with authors nationalities but it's not really readable without the list of values below
