How to define a mathematical function for a graph?

Question

Analytics

Colleagues hello
Please tell me the right direction of thought for solving the problem:
There is a time series of values ​​that defines some kind of graph.
Based on these values, it is necessary to find the closest function that describes this graph.
Graphs (values) are constantly updated, so you need to automate the search for such functions.
I would like to develop such an algorithm in Python for use in forecasting, the deadlines are very tight, and I have no experience in this area yet.
Thank you in advance!

Answer 1

I would like to develop
very tight deadlines
no experience
The good fairy is not up to you, so forget it.
Do not thank.

Answer 2

Graph what, functions? How is it set? On two axes? Please attach a picture.
If functions - that it has area of ​​definition.
Function - in mathematics, a correspondence between elements of two sets, established according to such a rule that each element of one set is associated with some element from another set.

I would like to develop such an algorithm in Python for use in forecasting, the deadlines are very tight, and I have no experience in this area yet.
Damn, people have been developing such algorithms since the 20s of the XX century, over the past 20 years they have programmed mountains of programs and libraries. But no, not only to learn - just to quickly familiarize yourself with it. What for? What if someone here in one message retold the whole theory with practice? I want to "develop an algorithm" - well, develop it, what's the problem. Deadlines are running out - well, negotiate with the customer. Or the message should be considered as a job offer - then in another section.
Okay, if you only need the right direction of thought - dig in the direction of "time series" (in the first word, the emphasis is on the last syllable). There is also a corresponding section - "forecasting based on time series" is called. Yes, at least enter Google into the search and follow the first links.
Good luck.

Guys, why are you so unkind, why so much negativity?
About fairies some banal snickering.
As for the time series, I’m just in the know, I immediately mentioned it in the question.
Okay, I'll manage, not in the first
