Not sure what you mean. All I have is:
chart.Axis(StandardAxis.PrimaryY).UseSeriesInflateWhenZoomed = true;
Zoom the chart, then pan - the y-range expands as I pan.
If I set UseSeriesInflateWhenZoomed to false, then panning behaves correctly.
I already have a CustomDataPanTool because I want to pan using the Shift key, so I have fixed the issue by using GetActiveChart(), turning off UseSeriesInflateWhenZoomed in the BeginDrag method, and back on again in the EndDrag method (keeping note of the settings on each axis so they can be restored).
It would be good if thsi was done automatically. I assume it already is when zooming?
Thanks
