This is great news! As much as I'm ecstatic that the overlapping algorithms will be corrected, I still think that a legend would make sense as an option. As part of this review of overlapping issue was there any indication whether a legend would be included in this release or possibly one further down the line in 14.2's dev lifecycle?
Hi AntonyC,
I suggest you refer to the Show legend for for Pie Chart ticket, where this behavior is discussed. We will update it once we have any news. Currently I cannot provide any estimation when it can be implemented.
When will this issue be fixed? I need a solution right away, or else I will have to find another control to show my diagrams.
The current version of the control does not provide the required capability. We are aware of this limitation but, I am afraid, we do not have any immediate plans to support it so I cannot promise that it will be implemented soon… Please add this thread to favorites to be notified when this feature is implemented.
I think it is absolutely shocking that you have no immediate plans to fix a but that was reported to you 5 months ago!
Hi
Are there any plans to solve this issue?
or is it already solved through https://documentation.devexpress.com/#Dashboard/DevExpressDashboardCommonPointLabelOverlappingModeEnumtopic
, if so how can you set the pointlabeloptions in a dashboard pie chart?
Thanks
This feature is not implemented yet. Currently, our JS chart controls used in the web dashboard viewer does not support resolving overlapping of point labels. This algorithm is complex and causes performance issues. We plan to improve this algorithm and introduce this feature in the future.
I look forward to the next release that will resolve this issue.
I have a same problem.
I hope this problem fixed soon.
This is really unbelievable that the control was let out of the door without any realistic ability (besides hover-over) to label the data points! The tired rhetoric of "will be introduced 'some time in the future'" is simply not acceptable for such a "basic" feature. I would have at least expected the ability to display a legend with the current broken state of the label overlapping, but that too is not available!
Hello Antony,
I understand your position and assure you that our developers work hard to provide this feature as soon as possible. We will inform you about any progress in this thread.

Dear Maxim
I'm afraid that this has become rather a critical issue for our company. We have a client that is extremely unhappy with the inability to correctly, at glance, have some label information on the data points. The entire reason we upgraded our license to Universal (and were looking to upgrade the rest of our dev team in due course) was to make use of this dashboard component and it's built-in export functionality.
In order for us to effectively manage the client's expectations we have to be in a position to give them some sort of time frame as to when one of the following could be achieved.
A Legend
Correct positioning of the labels
We do not see this as a "missing capability " but rather BROKEN functionality and feel that it should be far more prioritised than what this 17 month ticket would indicate! In addition it would appear that legends are readily available for the bar chart components, and even more frustratingly, when exporting the pie/donut charts, the labels appear correctly formatted!
I know that DevExpress has the policy of not providing any kind of release information, but in this case we are going to have to know whether the fix will at least be prioritised for the end of year major release.
Anticipating your response.

^^ Ditto. I upgraded to Universal also for the Dashboard and it's lacking in several areas for a what, 3 year old product? But this Pie Chart area is the worst. It makes the Pie nearly useless in certain situations. I'd love to see this be a super priority also.
Thank you for your notes. I understand your position. Currently, our team is working on this functionality, but it is not complete yet. For this reason we cannot promise now that it will be implemented in 14.2 but we hope that it will. Note that ASPxDashboardViewer uses JS Charts but WinForms Charts are always used on export. The WinForms Chart controls already provide the required functionality for a few years. Currently, we are working on JS implementation.
