The Small Chart message is not displayed when many Pie Series are shown on the chart

hello,
I have applied version v15.2.4 but the issue still exists just like before.
I uses 63 rows data, when I set the chart height to 900px, the pies can display.
but when I set the chart height to 600px or 300px, the chart display nothing.
Could you please help with it? thanks.

Hi Henry,

When the chart diagram area is too small, a special message should be displayed to indicate that it is necessary to increase the chart size to view all Series data. It would be helpful if you provide your sample project to illustrate the problematic scenario.

hello, Alex,
Thanks for your quick response.
Please check the attachment for the sample project. the data source is built-in, you can run it directly.

Hi Henry,
Thank you for your sample. I have checked it on my side and the small size message is shown. As Alex said, this is the correct behavior.
Can you see a small size message on your side? If not, please check that the correct assemblies version is used. You can do it by using the modules window when the application is working.
To show pies instead of a small chart message, you still need to change the chart settings.
As Vlad said before, you can hide series titles and replace them with series labels:

C#
WebChart.PivotGridDataSourceOptions.AutoLayoutSettingsEnabled = false;  
WebChart.SeriesTemplate.Label.TextPattern = "{A} : {S} : {V}";  

I am looking forward to your feedback.

thanks Anton,
If you see my demo, you should see the following codes:

It means that I am using Version 15.2.4.0 from your link, I also updated all the places  using previous version to the new version.
But I can see nothing in the chart when setting the chart to 300px or 600px, please see the attachment for the screenshot.
Is there any other configurations I need to check? I tried to upgrade devexpress 15.1 to 15.2, but it seems that they are installed at the same time, is that the cause?
thanks.

I unstalled devexpress15.1, deleted all files for 15.1 in GAC. and deleted 15.1 folder in Program Files folder, and restart the machine.
the chart still display nothing.

Hi Henry,

It appears that the latest intermediate build was used instead of the official maintenance release (v15.2.4) in our tests. I have corrected the "Fixed In" field value to indicate that the fix will be included in the next maintenance update (v15.2.5). You will need to request a hotfix build to test fixed assemblies on your machine.

Thanks Alex,
Since I have upgraded to 15.2.4.0, it seems that the hotfix in your link is for 15.1, can you give me a hotfix based on 15.2.4.0?

Hi Henry,

I have requested the v15.2 hotfix build and we will upload it once it is ready. Feel free to contact us if you notice a similar issue after installing the hotfix build on your machine.

ok, thanks Alex for your help.

You are always welcome!

hello Alex,
Is there any update about the hot fix?
I only receive an email that said DevExpress v15.2 is now available at Dec 16th, but I am not sure whether the hot fix is included.
Could you please confirm it? thanks.
