In our view model, the data range is expanded to include data outside of the X-Axis range. This is done to preserve the spline curve which is defined by previous points– doing this prevents the spline curve from changing drastically by including X number of points outside the range.

When the Draw function is called, the point context that was bound in is filtered to the X Axis range which leads to the spline curve changing as you pan (especially noticeable if it affects a peak).

How can I change this behavior to preserve the spline line?

Updated — Setting ResampleMode = None does not give me all the points.
