Hi everyone 😊   I have a dataset with three columns. Here is an extract: For a given line, the value for the third variable was obtained by fixing the first and second variables. The goal is to see how the third variable evolves for different combinations of the first and second variables.   I would like to make a graphic (3D or contour plot) where x= window, y=bandwidth and z=last_variance__first_variance, but I don't know how ... Could you please me ? 😅   Thank you in advance !               ... View more

I also want to save all those values in a dataset (one column per indicator, one row per sample).   Could you please help me ? 😅   ... View more
