matplotlib-users Mailing List for matplotlib

Hello,

I am using matplotlib as part of a data analysis tool, and I am having problems with a crash on Windows 2008 server when plotting data.  The application use to run fine, though I guess there was a round of windows updates recently (including some VC++ 2008 runtime updates).  No problems on Windows 7 professional with the same runtime updates.

I have tracked the problem down to the function call to update_path_extents in the _path.pyd module from transforms.py (L821 in 1.0.1).

Anyone else seeing this?

The event log shows that it is an uncaught VC++ exception based on this message:

You are going off the rails right here.  Don't try to mix pyplot and 
direct use of a gui toolkit.  Just don't do it.  Please.  If you want to 
use a gui toolkit directly, then start by understanding the 
embedding*.py examples in the user_interfaces subdirectory of the 
matplotlib examples.

Just a quick comment, according to your error message, you have a TkAgg
figure, not a WxAgg figure.  Maybe you should try forcing a particular
backend using "matplotlib.use('WxAgg')" at the beginning of the program?

I haven't read through the rest to comment on the validity of your
observations about show().

Hi all,

I need some help creating tooltips using pyplot figure rather than the
exisiting pylab example as in the link below
http://www.mail-archive.com/mat...@li.../msg00954.html
Well there is a specific reason for this. I am trying to write an
application which needs to call show() twice. matplotlib 1.0.1 solves this
issue by using show() in pyplot.

The code snippet i've used is

from pylab import *
import scipy
from wxPython.wx import *
import wx
import matplotlib.pyplot as plt
application = wxPySimpleApp()
tooltip = wx.ToolTip(tip='tip with a long %s line and a newline\n' % ('
'*100))
fig=plt.figure()
ax=plt.gca()
x=arange(10)
y=x*2
plt.plot(x,y)
plt.xlim(-2,15)
plt.show()
print 'passed the first show'
x=arange(10)
y=sin(x)
plt.xlim(-5,10)
plt.plot(x,y)
#print plt.get_current_fig_manager().canvas.SetToolTip(tooltip)
plt.show()
print 'passed the second show'

As per my observation, we need not create a new figure everytime we use
pyplot. Just plt.show() serves the purpose.
In case of using pylab show() then we need to call it once at the end of the
program or create a new figure everytime previous figure is closed and it
works too.
*Please correct me if my observation is wrong.*

I am stuck at the point  at tooltips now. How should I create tooltips on a
figure plotted using pyplot.

My program says there "*FigureCanvasTkAgg instance has no attribute
'SetToolTip'*"
plt.get_current_fig_manager().canvas.SetToolTip(tooltip)

for the current figure manager but in pylab equivalent
*from pylab import get_current_fig_manager as gcfm*
*gcfm().canvas.SetToolTip(tooltip) *
works.

Please guide me how to go about this issue.
