[Matplotlib-users] error on different mouse events

[darkside <in....@gm...>]

Hello  everyone,
I'm trying to do a program that opens two different plots and select one
point of each one with a mouse event. Here you have my example:


--------------------------
import pylab

def click(event):
    global x           # allow to change global variable
    if event.button == 1:
        if event.inaxes:
            x = event.xdata             # change global variable
            print " x - intern = ", x
            pylab.disconnect(cid)
            pylab.close()
return x

xlist = []            # list for x values
global x
#for i in xrange(4):
fig = pylab.figure()
ax = fig.add_subplot(111)
pylab.title('primera')
cid = pylab.connect('button_press_event', click)
pylab.show()
print " x - extern = ", x
xlist.append(x)
pylab.close()

fig = pylab.figure()

ax = fig.add_subplot(111)
pylab.title('segunda')
cid = pylab.connect('button_press_event', click)
pylab.show()
print " x - extern = ", x
xlist.append(x)
pylab.close()
--------------------------------------------------
The problem is that the click event only works with the first plot, in the
second one I get the plot, but not the mouse event. So my output is:
 x - intern =  0.696277915633
 x - extern =  0.696277915633
 x - extern =  0.696277915633
As you see, I only get the x-intern once.

Does anybody know what I'm doing wrong?
