Hi! That is familiar: loop goes on, but nothing visual happens. Normally when I don't get output of the loop, I put the output-line inside the function print(), and it works. But in this case it probably doesn't help. I am sure that someone here can help you, Rachida.

When I add the "for" loop to the code that produces before the graph I want, it does nothing : NO graph and NO error message. It seems to me that the command plot_ly and the for loop DO NOT coexist.

I think that it could be due to dimensions of CPM, not the structure of the loop. What kind of error message do you get? Is it: ”incorrect number of dimensions”?
