Created attachment 190830 [details] On the left the nested donuts as they exist. On the right the nested donuts with a space. I would like to specify a space parameter between the nested donuts. This make easier the labels layout (possibly by hand).
Thanks for the report, Jérôme There is an "exploded donut" chart type that automatically includes space between the two donuts, but neither the exploded nor normal types allow changing that spacing, it seems. In the object's content.xml, there is a chart:pie-offset[1] property that is set to 50 (i.e., 50% of the width of the thickness of the ring). Increasing this value does increase the spacing but also messes up the slices and results in a inaccurate outer ring.

The problem is that existing "exploded donuts" don't maintain the circular shape of each donut. The circular shape makes it easier to perceive proportions.
This would be particularly useful also for "refined-doughnut" charts, if we had them (I just filed bug 159180...)
