There is actually no other command needed than PLOT. You only have to plot different DATA. Example:

t=0:0.001:1; % ms
data=sin(10*t); % example data
plot(t,data) % full plot
figure
plot(t(11:51),data(11:51)) % from 0.01 s to 0.05 s

Well, may be you can do it. Say, tout is the vector of all time values and yout is vector of all signal values.

newtimevec = find(tout>=0.2,1):find(tout<=0.5,1,'last');
plot(tout(newtimevec), yout(newtimevec));

This should give you the plot you asked for.
