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?
Hello darkside,
I tried your example and it works for me (with mpl-svn) using GTKAgg and
doesn't work (like you reported) using TKAgg (Is this a bug?).
Maybe you can switch to GTKAgg?
Otherwise you should report the mpl-version you are using.
>-------------------------------------
import matplotlib
#matplotlib.use("TKAgg")
matplotlib.use("GTKAgg")
import pylab
>---------------------------------------
best regards,
Matthias

It's unbeliable. Yes, it works now!!! At least.............. I had spend a
lot of time with these!
So maybe is it a bug? Matplotlib developers: here you have a bug.
Thank you very much for your help, I coud never have thougt that it was the
problem.
