Python athplotlib.pyplot: Save the marked Check Buttons in text file

I'm doing a study about the shape of lightcurves. Therefore I plot my tables with the data points. Now I want different Check Buttons for the different shapes, i.e. non-periodic variability or periodic variability. After I checked all properties and go on to the next lightcurve, I want to save those properties in a new text file in the form of 'name' and 'chosen Check Buttons'.

I do not have any idea, how to work this out. Thank you for your help.

Cheers Benedetto
