Well..., I forgot to mention something, sorry ;-)
I already apply this trick: I use get_{x,y}lim and set_{x,y}lim.
Which works almost fine.
In fact, I use a grid, which is defined by xmin, xmax, dx & ymin, ymax, dy.
I don't want do display on the axes the number of points, but the real world
axis dimension.
If xmin=ymin=0 and xmax=ymax=500 with dx=dy=1,
the trick does work fine.
Now, if I set xmax=ymax=1000 but dx=dy=2 (so I have the same number of
points)
I have to use imshow extent option, because of the use of _xlim & _ylim.
Please see http://fredantispam.free.fr/a.png without extent option,
http://fredantispam.free.fr/b.png with extent option.
But in this case, after zoomed,
see http://fredantispam.free.fr/c.png
the trick does not work anymore: x & y limits are right,
but the whole data is displayed by imshow.
see http://fredantispam.free.fr/d.png.
Maybe I'm doing something wrong ?
TIA.
