slice missing in donut chart

[David]

Sometimes in my donut charts they are drawn with a "slice missing". The data points are all represented, the values all add up - it just doesn't go all the way around the circle. Anyone seen that, or have a fix?

Hi Karen,

I suspect that the background of the Graph is the same color as the slice that seems missing, which makes it invisible. In the attached file you can check a demo of a doughnut graph with such a slice (colored in white). In fact, the piece is there but it cannot be seen. You may set the Graph background to a different color to test this hypothesis.
If the above assumption is not correct and the issue persists you may open a support ticket and attach the report so that we can inspect it locally.

Thanks, but that is not it. The missing piece in your example has a data label, ours do not.

It doesn't always happen, but I can't nail down what makes the difference.

Hello Karen,

I noticed that you have opened a support ticket on the same topic. I will also paste the solution here as well so that members of the community can benefit from the information too. Here is the response:

"This actually is not a bug or an issue but a feature of the graph. In the attached file you can find a report which contains 2 graphs. They are the same except one property of the barSeries- ArrangeMode: 
1) the graph on the left has Stacked100 ArrangeMode, which is the default one. Here the size of the barSeries is set proportionally of the scans amount. 
2) the graph on the right has Stacked ArrangeMode where a slice is missing, due to the fact that it's axes, are arranged by slices' values (not by percents).

All in all, if the desired graph does not contain an empty slice, Stacked100 is the right choice for ArrangeMode of the barSeries."
