Akhilesh,
I am not totally sure that I understand what is your remaining issue. To
me, it seems that it is just a matter of building the “correct” common
abscissa vector to pass to ``fill_between``. See for example the
attached snippet for another kind of abscissa vector that would be
possible and maybe better suited to what you want.
Regards,
Adrien
