Hi, Mario,

Thank you or giving Kendo UI a test run.

The Kendo UI Charts have had no breaking changes since 2014 so I would need to know a little bit more about the way the chart is initialized. 

https://docs.telerik.com/kendo-ui/backwards-compatibility/2019-backward-compatibility.html

Can you confirm that this is the way Kendo UI is used in the project, if so, can you provide the full declaration?

https://docs.telerik.com/aspnet-mvc/getting-started/vb

Can you confirm that a compatible jQuery version is used and that it is referenced only once in the project?

https://docs.telerik.com/kendo-ui/intro/installation/prerequisites#supported-jquery-versions

Look forward to hearing back from you.
