Make a function out of it...
%%GraphFunction.m
[outputarguments] = function GraphFunction(inputarguments) %leave empty if no input/output arguments
%do some stuff
end
... create another file and call your graph function in a loop...
%%%Main.m
a = 100; %amount of times you want to run the GraphFunction
for i = 1:a
outp = GraphFunction();
%check if your output was ok
end
