Jean Claude, There are zoom buttons in between the timeline and the graphs windows. The apply to both (e.g. the two windows are always aligned). You can also use a scroll wheel. Also control-shift-+ and control-minus work for me on my mac keyboard.

Thank you Hy.
I saw the tiny + and - buttons. They work.
But on the French keyboard of my MacBook Pro, control-shift-+ and control-minus have no effect on the Analyze window.
If I use Command-shift-+ and command-minus, they don't act on the Analyze window but on the sky window which is in the back !
Great feature any how !!!!

I have a MBP as well. Try the "two finger down or up" swipe on the trackpad. When focused on the timeline it seems to zoom in X. When focused on the graph window it seems to zoom in Y.  As I said, if you have a mouse, the scroll button zoom also works. It's odd that my MBP zooms ok with the keyboard shortcuts, but your (French) keyboard doesn't. Perhaps try other characters besides +/-? Let me know if you figure out what I need to add for french.

I’ve been trying on a iMac (+ trackpad) and a MBP.
1/ Everything works beautifully if I use the + button, the - button and the slider bar implemented in the Analyze window.
2/ Using the trackpad gestures works on the Statistics graph. On the Timeline graph the zoom jumps from min to max even if I set the trackpad Trackin speed to minimum in the macOS System Preferences / Trackpad.
3/ Using the keyboard shortcuts : If I use Command-shift-+ and command-minus, they don't act on the Analyze graph but on the sky window which is in the back (confirmed again and again). Switching to a virtual US keyboard gave the same behaviour.
Conclusion : I’ll stop using keyboard shortcuts .
Have a nice day Hy.
