I am using SciChart to draw some graph on my application.
I use ZoomPanModifier to be able to zoom and drag the graph (with range limit).
<s:ZoomPanModifier ClipModeX="ClipAtExtents" XyDirection="XYDirection" ZoomExtentsY="True" ExecuteOn="MouseLeftButton" IsEnabled="True"/>
But the problem is when I drag to the edge of the graph, it will scale up automatically when I keep dragging.
Is there any way so that I can zoom in/out, drag graph (after zooming in), and no dragging and scaling up when I get to the edge of graph?

I tested this just now and ZoomPanModifier.ClipModeX=ClipAtExtents did exactly what you are asking for.
Using SciChart v4.0.4
Are you seeing something different?

With ClipAtExtents, I cannot pan the graph out of the edge, but I still can stretch the graph out when I keep dragging. I want to disable it.

I’m afraid I am unable to reproduce this issue. I have modified our Mouse-Drag to Pan Example to have ClipModeX=ClipAtExtents.

Below you can see the behaviour. When I get to the extents of the data in X, there is no stretching.
Can you please provide a code sample to reproduce? Preferably by modifying the same example.
Best regards,
Andrew

Sorry, it’s my mistake. I misunderstood about the graph behavior from my teammate. We got another problem. But I think I should post another question.
