Tout de suite il a des choses qui ne me conviennent pas et que je voudrais personnaliser (si c'est possible),
There are things I would like to change (sorry for french and english) starting with 1 and not using zero
I would like to begin to 1 not to 0, and changed all the labelled of the graph ?
I looked in sagemath doc but it not very explicative ...
Any comment comments and guide welcome.
Best regards
Henri
