Function from plot - Mensajes
WroteHow can I get a function from this plot ?
1. Probably from the expensive digitizer suggested by Richard [Mathsoft Collaboratory]
2. Piecewise from Tracer.
3. Try Mathsoft digitizer.
4. Smath difficult
At this point from the collected data set, fit a model function.
Cheers ... Jean.

Greetings,
That is a straight line on a semi-log graph; you can reference this handout: https://inside.mines.edu/~epoeter/_GW/LAB/EquationsOfStraightLinesOnDifferentTypesGraphPaper.pdf
Per this handout, your equation should be where:
May this be of Good Help;

Per this handout, your equation should be
y = b + m*log(x)
- m = difference in y over one log cycle of x
- b = y value corresponding to x=1
May this be of Good Help;

Hi. You can try this post Approximation of a functional curve in a digital image or this other one: Embedding images into a plot
Best regards.
