python - How to mathmatically represent a set of data -

-

i'm analyzing set of data shown on picture: data analyzed

if save data csv i'll end huge file. i'm trying fit polynomial first n data points , same next n data points. of course there needs constraint there smooth transition between first , second polynomial. @ point should able save coefficients of polynomials expect way more memory efficient raw data.

is there way in python? right approach? best way analytically describe curve?

another idea create bezier path data in order polynomial representation of data.

so think approaches? how solve problem?

i go classic solution , create table x , y coordinates. end thousands of records no problem modern applications. make simple things simple, think best approach.
