Suppose I have a plot, e.g. some function y(x) and I have plotted it. Now, if I wish to zoom a particular portion on the graph and show the zoomed portion inside the same plot (preferably by making a small box), is there any tool to do that with less computation (some GUI, etc.)?

No, I do not need a subplot. This needs to be done in the same plot. Something like this, which I have done by creating a box of some dimension and then placing it in a suitable position.

I am giving you the framework that you can use to do this the way you want. Every component of what you asked is there, they are just either placed or formatted differently. Tweaking and formatting is up to you.

r1 = [1:100]'.*rand(100,1);
figure;
a1 = axes();
plot(a1,r1);
a2 = axes();
a2.Position = [0.3200 0.6600 0.2 0.2]; % xlocation, ylocation, xsize, ysize
plot(a2,r1(50:70)); axis tight
annotation('ellipse',[.2 .3 .2 .2])
annotation('arrow',[.1 .2],[.1 .2])
legend(a1,'u')
