I am aware that for performance reasons that SciChart expects data to be sorted in the X direction. But is it possible to have it sorted in a descending order rather than the default ascending order?
Yes, data may be stored in descending order, however you will incur the performance hit for non-sorted data.
If you want to display data in reverse, what we suggest you do is to store in ascending order, and use the property XAxis.FlipCoordinates to reverse the axis direction.
Let me know if this helps,
