I am trying to do a data fitting for discontinued data points as shown in the graph.
the end goal is to come up with a mathematical empirical expression to satisfy a simulation
for example : f=(y0 + A1*exp(-X_loc/t1) + A2*exp(-X_loc/t2))

if what I am asking is possible, please include a screenshots on how to do it as I am not familiar with the software at all. if this is too much please help with what ever you can

and here is the data points if needed

Maybe you could use the regional selection tool to select part of the data and perform the fitting.
