Greetings!



What tools in Origin can classify the plots by shape (each plot is one column)?

Thank you.

What could be a workaround for this?
Can we somehow classify column vectors?

Agree.
I am thinking about doing multiple non-linear fit, then parse the reports and figure out the class of functions describing the data. Then pick the best function, fit each curve separately and classify a vector of function parameters.
