I would like to know how to plot a graph in a GUI like a scope or moving graph as the data point is simulated inside a for loop. and also how to move x-axis which is time in my problem along with the graph. For example how to plot a moving sin wave with respect to time.

A simple way:
n = 0:199;
for nn = 1:length(n)
plot(cos(pi/4*(n(1:nn))));
axis([1 100 -1 1]);
pause(0.2);
hold on;
end

Wayne's example contains all commands, which are necessary to solve your demands. Did you try to modify it?
