I have x and y. Image attached
How can I do at least three different curve fits that are appropriate for the data?

Take this as a demo example. In T and mu, you have to enter your data. Read about plot and polyfit.
T = linspace(0,4*pi,10);
mu = sin(T);
% Use polyfit to fit polynomial to the points.
T1 = linspace(min(T),max(T));
figure
hold on
plot(T,mu)
for n = 1:3
p = polyfit(T,mu,n);
% Evaluate the polynomial on a finer grid and plot the results.
mu1 = polyval(p,T1);
plot(T1,mu1)
end
legend({'Original','n = 1 fit','n = 3 fit','n = 3 fit',})
