Hi,
Thanks for the wonderful chart control provided from telerik. Is there a feature like dragging the chart area and datapoints gets updated depending on the drag. I tried with RadDrapDropManager but could not.

Using RadDragDropManager, i should drop the drag. that should not be the case for me...

Scenario:
1. RadChart holding queue with 1000 data points.
2. But the current chart view shows only latest 10 points.
3. If drag the chart area to left/right, then data points must get updated. (this must depend on drag sensitivity).
4. This is some thing like playing the chart area w.r.t to datapoints in the queue.
5. Should have an event warning me that i am at point 0 and point 1000 on the graph. (start and end of the queue).

Thanks,
Lakshman

Hello Lakshman,

You need to use the ZoomScrollSettings API exposed by the chart component. Here is an online example demonstrating how to set up the chart this way.

Hope this helps.
