[Matplotlib-users] using ginput with images -- axes are resized?

[Adam <ada...@gm...>]

hi, I am trying to use ginput with some images and for some reason it keeps
changing the axes with the mouse click.
I don't know if this is a feature or bug, but I would like it not to affect
my images at all.

here is a short example:

#---
from pylab import  ginput, imshow, rand

t=rand(50,50)
imshow(t)
x = ginput(1)
#---

this problem was also addressed in a post back in august:
http://www.nabble.com/ginput-changes-axes-limits-td18863282.html#a18863282
but it received no replies.

any ideas on whats going on?

thanks,
adam.

Confirmed: it's a big bug.  I suspect it has a simple fix, but I don't 
have time to look into it.

Hi adam


I found I needed to set the axis type to 'image'. 
The following code dosen't resize.

#------------------------------------------------------
import pylab

x1 = pylab.rand(103, 53)
fig1 = pylab.figure(1)
ax1 = fig1.add_subplot(111)
ax1.imshow(x1)
ax1.axis('image')
ax1.axis('off')
x = fig1.ginput(2)

fig1.show()

#--------------------------

cheers Eleanor
