Hypergraph 2D Plots: Applying a custom function to multiple curves

I have a bunch of test data curves in acceleration (m/S^2) from a UNV file.

I want to convert them to velocity in mm/s to compare with CAE pch file results.

In this case, this is two operations (scale, then integrate).

I general I want to be able to apply any user defined function to curves I have selected to either operate curve-by-curve with the same function, or perhaps calculate a single summary curve from all curves selected.

There are a few options:

Single Curve Math > Integral (to operate curve-by-curve)

Multiple Curve Math (for summary curves)

But these present a short list of limited options.

I understand there is a "StackMath" feature in recent versions, but I can't find any useful help for this, and it is not very intuitive. It also only seems to be supported for CurveXY (i.e. magnitude only) plots, and not complex curve data I am using.

It would be nice to just be able to define a formula that does the job, right?

Can anyone help??

Thanks,

Kristian
