Hi,
I was wondering if there is a way do a linear fit on 2 datasets simultaneously? It seems like you can only do a linear fit on one dataset with the figure fitting function?

I don't know what that function is. But why not just do it in code with the polyfit() function? Just stitch together the multiple x and y before passing in
coefficients = polyfit(multipleXs, multipleYs, 1);
