ImportError: cannot import name _get_all_lines, when trying to plot a grouped DF

[lJoublanc]

I have a DataFrame of stock close prices with a DatetimeIndex , close.

                     BARC:LON  HSBA:LON  LLOY:LON  STAN:LON
timestamp                                                  
2014-07-03 08:02:00   217.551   601.938   76.2100   1223.36
2014-07-03 08:04:00   217.200   602.100   75.8520   1220.00
2014-07-03 08:06:00   217.500   602.700   75.8700   1221.50
2014-07-03 08:08:00   217.750   602.400   75.9777   1222.50
2014-07-03 08:10:00   218.450   602.675   75.9440   1221.50

I want to plot these in separate graphs for each day, so I do:

for day,data in  close.groupby(close.index.date):
  data.plot(title=day)
  show()

But this throws

ImportError: cannot import name _get_all_lines

I can't find _get_all_lines anywhere. I recall doing this on my linux machine and it worked fine. This is running on Windows, pandas 0.14.1.
Also this works if I call matplotlib directly using plot(data), so the code doesn't seem to be at fault.

Are you using the latest master? _get_all_lines does exist (and tsplot no longer import it after #7717 because of refactoring).
https://github.com/pydata/pandas/blob/master/pandas/tools/plotting.py#L3024

May be an installation issue, otherwise the problem should always occur when importing tsplot.

[lJoublanc]

No, this is 0.14.1-1. It's from the Enthought distro, so it may just be they've packaged it incorrectly. Maybe I'll contact them. But the issue you're linking to is due to be released in 0.15, so it shouldn't affect 0.14, right?

[lJoublanc]

Ok, closing this issue as it seems to be a problem with the installation. Just restarted python and it works fine. Go figure!

Thanks to confirm. Yes, #7717 will not affect to v0.14.1 (I've assumed you're using dev version).
