Frequently asked questions

How do I enable percentage labels?

Turn on percentage labels; the chart draws ratios near slices and tooltips also show percentages.

Can values already be percentages?

Yes, as long as values are non-negative; displayed ratios are recalculated from their total.

What if there are too many categories?

Combine small categories first so the chart remains readable.
