x=get(h,'Xdata')
y=get(h,'Ydata')
plot(x,y)
can we do any operation on x,y after plotting?
how can we catch the values of y at different x values?

x and y are variables, in that case they are vectors 1xn columns, you can do many operations to them.
x and y have the same size, x(1) and y(1) correspond to the first point and so on until x(end) and y(end)

No, Paulo... I was joking with you because these questions are all the same.

You need to stop posting many questions on the exact same subject, take a deep breath, and figure out exactly what you are trying to do. We cannot read your mind. What does it mean to "catch the values of y at different x values"?? You have x and y, so if you want to look at them instead of plot them, do this:
[x;y]
If that isn't what you want, clarify with very descriptive words!

EDIT
Perhaps you mean that you want a function which will return the y for a given x?
f = @(X) interp1(x,y,X,'nearest');
f(x(1)) % Should return y(1)
