I am sorry for the fact that I am not able to make you understand the question. My question is, suppose I have the following plot
x=[0 20 40 60 100];
y1=[1 2 3 4 5];
y2=[6 7 8 9 10];
plot(x,y1);
hold on
plot (x,y2);
Now the x-axis of a particular graph is from 0 to 100 whereas the y axis is from 0 to 10. I want to zoom a particular portion of the x-axis say from 0 to 20 and plot it in the top right corner of the same graph. How do I do it?
