how to make a subplot.i did it but it has little problem.can anyone please guide me.here are codes,i combined them but didn't give the correct subplot.

here is the code.

%now for finding chi^2/dof.. dof in no.of exp.points-no.of free parameters.

there are two graphs i have to plot in single window which are ...

the cobination gives me a graph like this..

now the first part of theis subplot doesn't show me the fitting line as in the i have in the first individual plot...
