problem in showing the plot!!!

Community matplotlib-users

when I want to show the plot canvas, it doesn't stay at all, note that I need
to use "backendQtagg", I mean when I use "pylab" there is no problem in
showing the plot canvas, what is the problem? please help me.
I use this simple code:
"
from matplotlib.backends.backend_qtagg import FigureCanvasQTAgg as
FigureCanvas
from matplotlib.figure import Figure

x = numarray.arange(10)
y = numarray.arange(10)
fig = Figure(figsize=(5, 5))

axes = fig.add_subplot(111)
axes.plot(x,y)
canvas = FigureCanvas( fig)
xlabel('sahar')
canvas.show()
"
The plot just winks.

This is just a complete guess, but I wonder if you might be having conflicting backends. Try adding this to the beginning of your code.

import matplotlib
matplotlib.use(‘QtAgg’)

Also, I wonder if you should be using Qt4Agg?
