Hi Si kele,

The RadChartView component can handle real-life scenarios with constantly updating data. Every build-in series can be used to visualize the live data. I would suggest you check out our Live Data ChartView example in our demos.

Hello Si,

The chart is updated every 200 miliseconds and the WPF rendering engine need time to update the UI and it looks like the chart  "jump". What you can do to make it more smoothly is to decrease the time interval on which the data points of the line series are updated. For example, you can set it to 10 milliseconds. Also, you can apply a Direct2D rendering option to increase the rendering performance. I have extracted the Live Data example from the WPF Demo Application and apply the suggested modifications. I have also, created a video which demonstrates the comparing of the WPF and WinForms live data demo. Using the suggested approaches the two demos are very similar in rendering.

Hi Si,

Adding animation to the chart while constantly is updated is not supported by the RadChartView. With the current implementation of the control, I am not aware of a possible approach which could achieve such behavior.
