I have an issue with pie chart's where the chart width is small, the labels do not get cut (auto ellipsis) and the pie become very small if visible at all.

I have used the chart's GetSeriesMark event to add a line break, but this is done for every graph size.
Is there a way to get the rendered pie chart size, to add logic that will truncate the labels if the size is smaller that a certain threshold?.

Another issue, see that in the attached image there is a lot of "wasted" vertical area this is done since the arrow size is fixed for all the marks, is there a way to define that the arrow size will be automatically calculated to get maximum pie size?

An option would be using CustomXRadius and CustomYRadius property as discussed here.

Ok, in that case you can do something as what I did here. You may use that in the GetMarkText event.

I understand which is the problem here but I don't understand why it's related to arrow's size. I guess it's due to Circled property of pie series being set to true. Does setting it to false help? Otherwise, can you please elaborate on why do you think it's arrows size that causes this?

The problem is not caused entirely by the arrow size, what I meant was to say that in some case I would like to reduce the arrow size to have more space for the chart.

      pie1.Marks.ArrowLength = 10;

What I'm getting at is having a way of ensuring a minimum pie size, either by a built in way or by events.
