Thanks for the detailed answerS I will try to go one step further for the u=
nclear question.
I hope this will help other users too :)

Indeed I meant 'by default' and you answered partially my question.
I would like to disable only the veritcal zoom, not the horizontal one.
Is it possible ?

I am aware of tooltips in pygtk, and I would liek to use them on the axes o=
nly.
As I understood those axes are included in a figure which is a DrwaingArea.=
 But DrawingArea do not accept tooltip easily.
Did you implement a workaround to have a tooltip on the axes

I used the NavigationToolbar as a GTKToolbar and added a button with the fu=
nction I wanted.
This solved my problem

The histogram provide a similar plot to what I want.
I am currently using it, but when i zoom horizontally I can get very few an=
d large bars.
Therefore I would be interested in a simple curve fitted to pass through al=
l the tops of histograms.
This would make the picture more consistent throughout the zooming

If the curve was filled it would be even better :)

Within one Sublot I have thousands of small "lines" plotted. This takes tim=
e to draw and show on the screen
Within my software I would like to be able to filter interactively that inf=
ormation according to various criteria to show only few of them
In order to do that cost effectively I was wondering if matplotlib provides=
 an option to show/hide specific "lines" that I could turn on/off
That woudl avoid me to redraw the whole picture after 1 single change
