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)

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)
