Hello,
can someone tell me why my pie chart is disappearing when I call .refresh()?
Here is a snipped illustrating my problem:
https://dojo.telerik.com/uGijuvOw/2
It works fine when I set the data as the dataSource and call dataSource.read() prior to .refresh(). But for our use case it would be more convenient to have the data embedded in the series.
Regards,
Matthias

Hello, Matthias,
Thank you for the example.
This occurs because the refresh method expects the Chart to be bound to a dataSource.
In cases where the dataSource is not used, we can recommend the redraw method of the Chart:

https://dojo.telerik.com/uGijuvOw/3
Apologies that this is not mentioned in the documentation. We will fix it.
