Hello, 

We are changing our chart library from LiveChart to Telerik but there we are facing a problem.

We want to be able to smoothly move each point of a line series to its new location when the value of a point is updated in the model, wich is very straichtforward using LiveChart. We can manage to redraw the chart with the new value out of the box but it seems like points jump from one place to another and we can't find any litterature about how to move them smoothly.

Is that even possible using Telerik? How?

Any help will be appriciated

Hello Emilie,

You can see how to create a live chart in the LiveChart RadChartView example from the WPF Demos application. Also, you can check the Animations article. However, your requirement (value change animations) is not supported out of the box. To achieve this, you will need to write custom logic that animates the data points. For example, you can update the value property of the data point from the original value to the target one using a timer.

I logged a feature request to introduce this type of animation in the Telerik charts. You can find it logged in the UI for WPF feedback portal. I also updated your Telerik points.
