Hi,
My issue is quite simple: I reload several times an image
with the colorbar enabled, and thus, I have several colorbars, not only one.
How can I disable this, and thus, get only one colorbar ?

Not really ;-), but no problem.
I got a fix.

Hi,
Please look at the short example attached showing the issue.
I want to display only one contour line, with value 0.8.
Obviously, the color associated with this contour line is bad
(blue instead of red color).
I think the reason is that the contour has its own colormap,
so for only one valu

Exactly, perfect !
Thanks a lot.

Hi,
I want to keep the image zoomed to the same factor for all my images.
If I try
ipython -pylab
imshow(rand(50,50))
then zoom with the mouse and redo
imshow(rand(50,50))
the zoom factor is not kept, ie xrange/yrange are still (0,50).
How can I keep the zoom factor ?
TIA.
Cheers,

Yes :-)
You only need to set extent to the const xmin/xmax & ymin/ymax
and not those you get with get_xlim & get_ylim.
Sorry for the noise.

Thanks anyway, Jouni, I fixed my issue thanks to you ;-)
You showed me that the get_?lim methods were right,
so I followed my feeling further.

How can I know if the displayed image has been zoomed or not
(I mean not on testing xlim & ylim) ?

I guess you should try scipy-user at scipy.org ml.

Ok.
Well, running mpl examples (say image_demo.py),
you can see the point coordinates under the pointer.
Good point ;-)
I would like to have the scalar value under the pointer to be displayed
too.
How could I do this ?

Hi,
Is there any tarball for ml archives ?
In fact, I'm looking for something related to values probing (with a
pointer,
for example).
So I want, before asking, to have a look in the archives.

Hi the list,
I have looked for in mailing-list archive, but did not find anything
relevant.
I use matplotlib 0.87-5 and I want to try some examples concerning fonts

When I run fonts_demo.py, I get the following messages :

Hi the list,
Is it possible to have some curves not legended ?
A sample example is better :

How can I do this ?

in order to keep the text lined up right.
