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 ?
Cheers,

You may need to post a small code example so we can see what you are doing; but an interactive example using ipython -pylab may give you enough information to answer your question:
im = imshow(rand(20,20))
colorbar()
im.set_data(rand(20,20))
draw()
im.set_data(rand(20,20)*5)
im.autoscale() # to change the colormap limits
draw()
etc....

Hi ,
Not really ;-), but no problem.
I got a fix.
The trick is to pass axes colorbar as argument to colorbar function:
def update_colorbar(self):
if (self.cb is None):
self.cb = self.display.figure.colorbar(self.img,
ticks=self.cbticks,
format='%g')
else:
self.display.figure.colorbar(self.img,
self.cb.ax,
ticks=self.cbticks,
format='%g')
that works perfectly.
Cheers,
