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

[Thomas B. <tho...@ya...>]

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

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,
