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.
Cheers,

You can search the user and developer archives here:

It's also archived on gmane, which has a different interface that some prefer:
http://dir.gmane.org/gmane.comp.python.matplotlib.general
Or, in a bind, sometimes using Google with "matplotlib-users" in the search string can return different results.

Yes, but with "probing" keyword,
results are not relevant:
"Could not fire up pylab in Japanese XP"
I can't believe that no one has asked before about this issue
Unfortunately a lot of the mail archive search algorithms are pretty
poor. I subscribe over gmail, which has decent search, but I do not
have the entire archives. I have a lot of the archives, particularly
the earlier years when I was using a UNIX mail server and client, but
now that I have moved over to gmail I do not have the recent archives
in flat file or tarball.
But you can just ask us -- maybe we can help.

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 ?
In fact, I use mpl in a traits app,
which looks like this:
http://fredantispam.free.fr/mpl.png
In my traits app, no point coords under pointer are displayed.
Am I missing something obvious ?
snippet code:
da = self.display.axes
self.img = da.imshow(self.current_data.array,
vmin=self.vmin, vmax=self.vmax,
cmap=self.cmap,
interpolation=self.interpolate_colormap_method,
extent=extent,
origin=self.origin,
alpha=self.opacity)
self.display.figure.canvas.draw()
TIA.

Since all sorts of data can be displayed in am mpl window (e.g. a
plot, a contour...) you have to tell it how to access the correct
scalar value to display. You could do this with the
motion_notify_event. Register it during init, something like:
self.canvas.mpl_connect('motion_notify_event', self.mouse_move_callback)
then in mouse_move_callback:
def mouse_move_callback(self, evt):
xpos, ypos = evt.xdata, evt.ydata
val = self.data[numpy.floor(xpos), numpy.floor(ypos)]
status_str = "x: %4.2f y: %4.2f I:%4.2f" \
% (xpos, ypos, val)
self.SetStatusText(status_str)
where data is your image variable. This works in a wx.Frame object,
which has a SetStatusString method for displaying the values. I'm sure
you could find an equivalent in your traits app.
Hope that helps,
Gus.

Thanks, I'll look at this asap (as I got other stuff "on fire").
BTW, I can't ever get (in fact, I don't know how) working
the coords to be displayed in my traits app.
I guess this is more related to traits, not to mpl.
But the "mpl embedded in traits app guru" is on holydays for now.
Let's wait...

For what it's worth, mpl embedded in wx also _requires_ the use of
motion_notify_event to get co-ordinates to display. It doesn't happen
by default except in stand-alone mpl as far as I can tell.
