is it possible that the filter is somehow cutting out too much data?
If the data is the same in two columns and both are used for the graph, one for points and one for the smoother, I guess this could happen. I haven't run in to it before.
the smoother requires at least two points (for a line) or 3 points for a fitted line.
Could that be the problem?
