Hello,
Could you tell me how to finish Multiple Fits towards the same curve within one graph? Fox example, the linear Fit, polynomial Fit, Sigmoidal Fit.
And How to carry out the Fit towards some curves simultaneously in one graph?

Thanks!

I'm not sure what you mean by "finish". The relevant commands on the Tools and Analysis menus plot the fit curves in the same graph and record the fit parameters in the Results Log. What else do you need?

This Knowledge Base article should help...

A multiple curve fitting add-on is also available on the File Exchange...
