Here's a starter. You can add the other equations and labelling
V = @(S) 0.349109 + 6.00940*S + 0.047467*S.^2;
S = logspace(-2, 2);
semilogx(S,V(S)),grid
xlabel('Sommerfeld Nbr'),ylabel('Temp Rise Dimensionless Variable')
axis([0.001 10 0 7])

ı know they are given to me. but ı ask you is it possible to obtain the equation of the chart if it is not given to me? for example can ı obtaion the equation of position with respect to S ( the chart that ı put below)? ın the chart which is given above temperature rise with respect to S equation is given to me. but ı wonder what if its not given. can ı create ıt by matlab? because ı use some digitalization applications but they are not good. there are a lot errors

You should be able to pick off several points and fit a quadratic in S to them.
