Plotting libraries in python?

Question

Python

Hello!
Please advise a library for python`a for plotting functions, etc. Two features are needed:
1) the ability to pass the library a callback function that performs calculations, calling which the library itself builds a graph.
2) the ability to create a graph for several points, so that the library itself completes it to infinity (or to a specified maximum).
3) the ability to get x from the graph for a given player and vice versa programmatically.

Answer 1

matplotlib

Answer 2

Not sure if there is a ready solution. But this functionality is easy to implement based on numpy and scipy
1. Change the data and draw the graph in your own loop.
2, 3 Use the interpolation function .
