How to change step size of differentiation

I need integration, differentiation of some function TF1. However, I do not want to use the default setting.
(1) How to change the step size of differentiation?
(2) How to change the number of intervals to calculate the integration?
(3) What are the default values?


I have no idea what you are asking about but maybe you just want to play with TF1::GetNpx and TF1::SetNpx which are related to the number of points used to draw the function.

BTW. What concerns “intergration”, see for example:
