Hi, I have a scatter plot. Is there a way to show the change point for data on the scatter plot (calculating it on the scatter plot)? Or anyway built-in feature for this statistical metric). either in 2019 or 2020 versions!|
Thanks in advance!

@dpb sry I cannot share the data here. But they are two simple 365 by 1 arrays. Assume X and Y. So I want to sort Y values based on X (something like scatterplot which finds the correlation) then detect change points in Y.

"change point" is not a statistical metric. "Change point" is something that is perhaps deduced by examining statistical measures.

See if <Piecewise Polynomial> is what you're asking for...
