So I would like to have the ticks of the vertical axis on the right instead of on the left.
The "best" I have been able to get is this:
by plotting between -9500 and -187 (for -186 it does the same as before).
But this is not very elegant.
I do not know if matplotlib has an option for this, and in that case, how to tell SageMath to use it (I have been unable to access tick_params()).
I do not include any code, as I think it is irrelevant to the question.
