Improve pie chart setting

Hi,

Pie chart is commonly used in dashboard but when trying to show %ARR per product for ideas coming from SF-Aha integration, I realized this cannot be done in a pie chart and only in pivot, which is less "executive friendly" to be shown in a dashboard. Today in the pie chart we can only set one value – sum of or average. It would be nice being able to choose multiple values in the pie chart to get sum of average values.
