Newbie question/closing a figure-window

Newbie question/closing a figure-window
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(10000)

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 call

return self.func(*args)

File “C:\Python25\lib\idlelib\MultiCall.py”, line 151, in handler

r = l[i](event)

File “C:\Python25\lib\idlelib\ScriptBinding.py”, line 166, in run_module_event

interp.runcode(code)

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.

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.

Dear Wayne,

2009/1/13 Hajas, Wayne <Wayne.Hajas@...2447...>:

Should I expect IDLE to work with matplotlib? Should I try and figure out
Ipython instead?

Definetely, IPython *is* the environment to work with Python plus
Matplotlib, as it already includes built-in support for interactive
use of MPL (and in general too, as IPython offers a lot more resources
than IDLE).

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.

Enthought Python includes a lot more pre-packaged Python libraries
than Python(x,y) -- for example, the wxPython GUI library
(unfortunately, in my surely biased opinion, the developers of
Python(x,y) did not include wxPython in their distribution), and MPL
Basemap toolkit.

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.

Well, none of these pre-packaged distribution is really "up-to-date",
as the development versions of the libraries (those available only via
svn) will of course never be included.

Thanks to everybody who responded to my original post.

I think Massimo put it best: IDLE does not play well with matplotlib. I
will just have to learn how to be effective with ipython.

This may be true that idle doesn't play well with mpl, but I don't
know why it should be (it used to work ok). It is definitely in your
interest to learn ipython (it's easy) but if you want to try idle,
make sure you read

  http://matplotlib.sourceforge.net/users/shell.html

Also, when this came up in the past, people suggested to run idle with
-n and set the os.environ['PYTHONINSPECT'] = '1' evnironment variable,
eg
