Pie chart is twisted after using PieLabelMode.SpiderNoOverlap

Hello,

Nevron software was upgraded in our project (from version 6 to 10).

In pie charts, we want to use the value PieLabelMode.SpiderNoOverlap. Where most pie charts (we display multiple charts in a control) lookes ok (after using this enum's value), other pie charts looks are twisted.

I added an attachment of the good old pie chart (without using SpiderNoOverlap value) and an attachment of the new and bad pie charts (after using SpiderNoOverlap value). As I said, we display more then one chart in a control, and that's why the pictures shows more then one pie chart.

Does someone knows why this is happened, and how I can solve this problem?

Hello,

Please send the source code that you use to configure the problematic pie charts. You can post it here or send it to our support e-mail.

Best Regards,

Same thing happens to me.
It only happens when there is a pie slice that is about 99.9% of the whole pie and the label is also big (like 999,999,999 when all other slices are about 20).
When you set the pie to SpiderNoOverlap mode it grows so big you cant even understand it.
Sorry cant post my code here either...

Hello Tal,

We fixed this problem some time ago, you can download the latest version of the component from our website and check if it works OK.

It doesn't fix it. In fact - it happens more often!
I managed to find the source of the problem though - it only happens when there are less then 3 labels to show on the chart.

I hope you'd really fix it this time..

Hello Tal,

It appears that this is a different issue. We managed to reproduce the problem I hope we will fix it for the next release.
