This might be a sort of vague question, but if I have a plot say that I don't know the data points for, how can I go about trying to find a fitting function (basically a functional form) for the curves I'm looking at?

Basically I have a figure I got from a journal paper that I want to parameterize with two variables of interest, come up with some sort of functional form for it whose parameters I can tune to change what the curve looks like and then put this into some code that I have.

I'm not really sure where to start with this. I know that there fitting procedure I can use if I have a guess at the functional form but maybe want to tweak the exponents or coefficients say, but I'm not really sure if this applies in this situation.

Sorry if this is to general and vague.

Thanks much.
