Thanx for the tip, but this is not the exact way of finding the point
values. I can not be sure that i am pointing exactly the right location
on the graph. And also i want to save the graph after i showed the
values, so how can i make octave show the values, instead of a manual
interaction?

this can be done with the "text" command, for example try the following:

x = linspace(0,1,100);
y = rand(size(x));
plot(x,y,'y',x(10:10:90),y(10:10:90),"x")
for ii = 10:10:90
text(x(ii), y(ii), sprintf("(%1.2g, %1.2g)",x(ii),y(ii)));
endfor
axis([0 1 -.1 1.1])
