Re: [Matplotlib-users] xticks not lining up with data

2015-06-17 Thread Ted To 
Thank you, that worked.  And also showed me why the xticks were 
mismatched -- apparently my index was not sorted.

Then convert them to date objects? Also, I am guessing that the length of
indices.index is not the same as indices.carli, which could also be the
reason for a ValueError. So you would need to use whatever pandas variable
that indices.index derived from.

Re: [Matplotlib-users] xticks not lining up with data

2015-06-17 Thread Ted To 
Unless I recall incorrectly, I think I am using set_xticklabels because 
indices.index are strings.  When I tried specifying 
ax.plot(indices.index,indices.carli) I get a ValueError.

Re: [Matplotlib-users] xticks not lining up with data

2015-06-17 Thread Benjamin Root 
Why are you calling ax.set_xticklabels()?. Why not pass the x values to
ax.plot() along with the y values? Then you won't need to set the labels
because matplotlib will do it for you.

[Matplotlib-users] xticks not lining up with data

2015-06-17 Thread Ted To 

Hi,

I'm having a strange problem and I don't understand why this is
happening.  I am plotting the dataframe in: http://pastebin.com/C0Pt0iYd
but I'm getting too few tick marks.  My code for the plot is:

  fig, ax = plt.subplots()
  plt.rc('text', usetex=True)
  fig.autofmt_xdate()
  ax.plot(indices.carli,'b-',label=r'\textsf{Carli}')
  ax.plot(indices.geomean,'g-',label=r'\textsf{GeoMean}')
  ax.plot(indices.laspeyres,'c-',label=r'\textsf{Laspeyres}')
  ax.plot(indices.paasche,'m-',label=r'\textsf{Paasche}')
  ax.plot(indices.tornqvist,'y-',label=r'\textsf{T\"ornqvist}')
  plt.xlabel(r'\textsf{Month}')
  plt.ylabel(r'\textsf{Index value}')
  ax.set_xticklabels(indices.index)

Any ideas what I'm doing wrong?

Thanks,
Ted
