[ROOT] Zoom again

Hello!
Well, thanks for the suggestions but they both are not quite what
I was asking for. Assume I have a picture like this:

20 |
   |
15 |     /\
   |    /  \
10 |   /    \
   |  /      \
 5 | /        \
   |/__________\____
 0  5     10    15    


As you see Ymin = 0 and YMax = 15. Then I zoom X axis, 
say from 7.5 to 12.5

20 |
   |
15 |    / \
   |  /     \
10 |/         \
   |         
 5 |          
   |_______________
 0 7.5         12.5    


Y axis range will stay the same but now Ymin = 10 and Ymax = 15 (min and 
max of the graph in the new X range, not min and max of the Y axis!). 
How can I get these numbers? If I use

h2->GetYaxis()->GetXmin();
h2->GetYaxis()->GetXmax();

I will not get Ymin and Ymax of the points on the picture but min and
max of the axis (0-15 in both cases).


Regards,
Anton
