Re: [Matplotlib-users] Newbie question/closing a figure-window
I have had similar experiences with IDLE on both XP and Ubuntu 8.04 and
as a result I use IPython as much as possible. On XP I would recommend
that you install Python(x,y), 2.1.9,
http://www.pythonxy.com/foreword.php
which includes IPython(0.9.1) and IDLE(1.2.2) as well as many other
useful programs.
The example you gave runs under IPython with the command
run -i programname.py
and gives a plot which can be accessed independently of the IPython
shell. In other words you can execute commands in the shell while the
plot is still on the screen.
Hope this helps
Richard
p.s. I, like you, would still be interested in knowing why IDLE crashes
when a .py script is run twice.

I'm just getting into matplotlib and python. My apologies if I just
haven't found the obvious documentation.
I am running XP/Enthought Python 2.5/Idle/matplotlib 0.98.5.2
I run one of the scripts from the tutorial:
import numpy as np
import matplotlib.pyplot as plt
mu, sigma = 100, 15
x = mu + sigma * np.random.randn(1)
# the histogram of the data
n, bins, patches = plt.hist(x, 50, normed=1, facecolor='g',
alpha=0.75)
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title('Histogram of IQ')
plt.text(60, .025, r'$\mu=100,\ \sigma=15$')
plt.axis([40, 160, 0, 0.03])
plt.grid(True)
plt.show()
A window with the figure appears on my screen. It looks very nice.
But now my PYTHON-Shell screen is dead.
I can go to the figure window. I right click on the upper-border to
close the window. I get the following error message on the
PYTHON-Shell.
Exception in Tkinter callback
Traceback (most recent call last):
File C:\Python25\lib\lib-tk\Tkinter.py, line 1403, in

File C:\Python25\lib\idlelib\PyShell.py, line 701, in
runcode
self.interp.restart_subprocess()
AttributeError: ModifiedInterpreter instance has no attribute
'interp'
And the shell-window is still dead. I can't do anything else until I
close all my Python windows.
Is there a better way to close the figure-window?
Should I expect IDLE to work with matplotlib? Should I try and figure
out Ipython instead?
Should I look for a Tkinter installation? My current version is
Revision: 50704?
Any help or suggestions are appreciated.

PIL) not included in Python(x,y). Hope this helps. Best regards, Just to clarify your comments re: Python(x,y) as I wasn't sure myself I checked on http://www.pythonxy.com/download.php . The full edition of Python(x,y) 2.1.9 contains all of the software you mentioned(PIL, matplotlib, IPython, Enthought Tool Suite) while any of these missing from the basic and light editions can be added as plugins. Another thing I like about Python(x,y) is that it is updated frequently so that you are always working with the most up-to-date software without having to compile it yourself. rj Richard Johns rjo...@tbaytel.net -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
[Matplotlib-users] plot3D problem
I have been trying the 3D matplotlib examples in http://www.scipy.org/Cookbook/Matplotlib/mplot3D using ipython as follows: python -pylab -p scipy import matplotlib.axes3d as ax3d u=r_[0:2*pi:100j] v=r_[0:2*pi:100j] x=10*outer(cos(u),sin(v)) y=10*outer(sin(u),sin(v)) z=10*outer(ones(size(u)),cos(v)) a=ravel(x) b=ravel(y) c=ravel(z) fig=figure() ax=ax3d.Axes3D(fig) This works fine for ax.plot_wireframe(x,y,z) and ax.scatter3D(a,b,c) but when I try ax.plot3D(a,b,c) the following errors appear: x.plot3D(a,b,c) --- exceptions.TypeError Traceback (most recent call last) /home/rj/ipython console /usr/lib/python2.3/site-packages/matplotlib/axes3d.py in plot3D(self, xs, ys, zs, *args, **kwargs) 488 def plot3D(self, xs, ys, zs, *args, **kwargs): 489 had_data = self.has_data() -- 490 lines = Axes.plot(self, xs,ys, *args, **kwargs) 491 if len(lines)==1: 492 line = lines[0] /usr/lib/python2.3/site-packages/matplotlib/axes.py in plot(self, *args, **kwargs) 2129 lines = [line for line in lines] # consume the generator 2130 - 2131 self.autoscale_view(scalex=scalex, scaley=scaley) 2132 return lines 2133 TypeError: autoscale_view() got an unexpected keyword argument 'scalex' Also, moving the mouse into the blank figure window gives many errors like: File /usr/lib/python2.3/site-packages/matplotlib/proj3d.py, line 243, in proj_trans_points return proj_transform(xs,ys,zs,M) File /usr/lib/python2.3/site-packages/matplotlib/proj3d.py, line 226, in proj_transform return proj_transform_vec(vec,M) File /usr/lib/python2.3/site-packages/matplotlib/proj3d.py, line 185, in proj_transform_vec vecw = nx.matrixmultiply(M,vec) TypeError: unsupported operand type(s) for *: 'NoneType' and 'float' I am using Scientific Linux 4.4 i386 Scipy(with ATLAS) numpy from svn, rev. 2292 3375 respectively MatPlotLib 87.7 Any ideas about what is going on?
