I am trying to change the underlying data for my plot via a pick event,
except that the matplotlib examples for picking show a couple of functions
with predefined signatures and I can't seem to figure out how to modify my

Here is a minimal example of what I am trying to do:
[code]
import matplotlib.pyplot as plt
def pick_rlines(art,mouseevent):
button = mouseevent.button
key = mouseevent.key
wsf.nnn = 4 # -- how to modify wsf.nnn from here?

class AAA():

class BBB():

wsf=AAA()# when it is defined here?
wsf.nnn=0
GR = [1.0, 2.0, 3.0, 4.0]
fig = plt.figure()
ax = fig.add_axes([0.1,0.1,0.75,0.75])
ax.set_aspect(1)
rlines = ax.hlines(GR,0.0,4.0,picker=pick_rlines)
fig.canvas.mpl_connect('pick_event', pick_handler)
plt.show()
if __name__ == '__main__':
the = BBB()
In the code as you've written it, the is in the global namespace, and so
your pick event handlers can see that variable. So you could write:
def pick_rlines(art,mouseevent):
button = mouseevent.button
key = mouseevent.key
the.wsf.nnn = 4 # the is in the global namespace
But a cleaner design would be to make the pick handler a class method of
class BBB, eg
class BBB:
def __init__(self):
self.fig = blah_blah...
self.fig.canvas.mpl_connect('pick_event', self.pick_handler)
self.wsf = blah_blah...
def pick_handler(self, artist, event):
self.wsf.nnn = 4 # wsf is in the class namespace

Re: [Matplotlib-users] PyQt4 FigureCanvasQTAgg Subclass segfaults with Matplotlib 1.1?
Thanks for the suggestions, Darren. I spent some time going through older revisions of Matplotlib (and Numpy and SciPy) and it turns out that it isn't an issue with Matplotlib as I originally suspected, but rather how I went out updated an imshow-based plot. Previously I was attempting to plot an image first, then set then use the result to create a FigureCanvasQTAgg instance: import matplotlib.pyplot as plt figure = plt.figure() self.axes = figure.add_subplot(111) self.axes.imshow(...) self.figure = figure FigureCanvasQTAgg.__init__(self, self.figure) This works in some environments and it happened to work at the time I originally developed the code, but is not the best way to do things. A better way is to first instantiate a Figure instance: self.figure = Figure() self.axes = self.figure.add_subplot(111) self.axes.imshow(...) FigureCanvasQTAgg.__init__(self, self.figure) For now this seems to do the trick. If anyone knows of a better way to do things, please let me know. Thanks!

Re: [Matplotlib-users] where is line after remove?
Ben Yest It is called remove but not destroy ;) Given that the relim takes in count the invisible lines, I thougth it was planned that you could remove and add the lines from its axes.

Re: [Matplotlib-users] missing documentation on homepage: subplots
I don't think so, I thought I paid attention when I noticed the choice between 'subplot' and 'subplots'. In any case, now there does not seem to be a choice, there is no 'subplots'...there is only 'subplot'...was this page modified? 'cause the Last Updated notice at the bottom of the page still says Oct 30, 2011.. ...I am confused. -- View this message in context: http://old.nabble.com/missing-documentation-on-homepage%3A-subplots-tp33496068p33497211.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Keep Your Developer Skills Current with LearnDevNow!

plt.show()
plt.close()

I can't see anything obiously wrong in your code or your data --I did
not dive too deep into it though. What is weird is the traceback:
