Line charts have a great option - spline which smooths curves.

I don't see such an option for scatter charts with lines.
What is the best way to smooth a scatter chart graph.

The Line chart uses Catmull-Rom splines to generate curvy lines - but that (I think - since only the Y points are given to the spline function) relies on having equally spaced points across the line - which isn't always a given on a Scatter chart.

Plus theoretically the line could double-back on itself (ie end up going in both directions).

So the spline wouldn't work on the Scatter I'm afraid.
