RE: [Matplotlib-users] problem reading data file in stock_demo.py

John,

Tks vm for your reply.  I was able to get the script to run with your
"examples" directory.  Much appreciated.  

However, when I unzipped the py.60a.zip files over my site-packages
directory and re-ran the script, I got the following error:

C:\Matplotlib\matplotlib src\examples>python stock_demo.py
Traceback (most recent call last):
  File "stock_demo.py", line 4, in ?
    from matplotlib.matlab import *
  File "C:\Python23\lib\site-packages\matplotlib\matlab.py", line 134, in ?
    from axes import Axes
  File "C:\Python23\lib\site-packages\matplotlib\axes.py", line 9, in ?
    from artist import Artist
  File "C:\Python23\lib\site-packages\matplotlib\artist.py", line 4, in ?
    from transforms import identity_transform
  File "C:\Python23\lib\site-packages\matplotlib\transforms.py", line 181,
in ?
    from _transforms import IDENTITY, LOG10, Func, FuncXY, PolarXY
ImportError: cannot import name IDENTITY

C:\Matplotlib\matplotlib src\examples>

Is version 0.54.2 not the correct starting point for doing this unzip?  If
solving this is a hassle, I don't mind going back to the old 0.54.2 and
waiting for the bug fixes that come with the next proper release.

Tks again,

Tom

Where are you getting the examples dir from?  I notice that I failed to
upload a zip file that includes the examples directory with the
0.54.2 release.  Are you using one from a previous release?

It looks like you make have a corrupt stock data file.  I was able to load
the stock_demo example using both the numeric and numarray win32 builds,
with either numerix setting in my rc file.

I did, however, discover a bug in the navigation code in that example
related to data clipping.

The zip file below fixes the latter problem.  Unzip it in your site-packages
dir (do not remove the old matplotlib code, just unzip this over it)

  http://nitace.bsd.uchicago.edu:8080/files/share/matplotlib-py.60a.zip

And get a fresh examples dir from 

 
http://nitace.bsd.uchicago.edu:8080/files/share/matplotlib-examples.60a.zip

Hope this helps,

Something is wrong with your installation.  My transforms.py line 181
is something different.  _transforms should be providing IDENTITY.

We're planning on doing a release in the near future, so if you can
wait for the new installer, that would be easiest.
