Hello Duy,

In order to achieve the desirable functionality you can use RadSlider's client side API along with RadChart.
You can find an attached sample project to this message illustrating how to create zooming RadChart with RadSlider.

The example shows how to apply the zoom to X, but you can further extend it to either apply the slider's value to both X and Y directions or use another slider for Y. You can find more information about RadSlider and RadChart Client-Side API  here and here.

Hope this helps.

Best wishes,

Hez, I tried this, and zes, he zoom function works, but the RadSlider becomes reset after the radchart is updated, which beats the purpose of it...why is this or how can i go around it?

Hello,

One possible option in this case would be to use the api to reset the scroll. More information on this is available in the following article:

I hope this gets you started properly.
