I am trying to programmatically update the Chart data during runtime to display live data. The Chart does not seem to refresh and show this change in the viewport.

I've tried:

• using an Observable Collection;
• creating a new collection instance and reassigning the Data parameter;
• calling the Refresh method;

The result is the same - the Chart does not react to the data change. This applies to other component parameters as well.

A possible workaround for the time being is forcing the Chart to re-render. To do so, you may wrap the Chart in a custom component and call StateHasChanged() in this component when the data is updated.

Here is a runnable sample: https://blazorrepl.telerik.com/wxEzwxbJ24WDjnMp11.
