zoomInBoth and zoomOutBoth functions

Hello,

I created a JFrechart graph and I would likte to zoom in or out when I use the mouse wheel.
For that I used a MouseWheel listener and I used the code that I find on this webpage : viewtopic.php?f=10&t=22919

Whatever are the values of the parameters of the functions "zoomInBoth" and "zoomOutBoth", the center of the zoom is the center of the window and not the values that I choose.

Do you know why ?

Thank you for your help.
Have a good day.
