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
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.

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.

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.

Thank you, that worked. And also showed me why the xticks were mismatched -- apparently my index was not sorted. On 2015年06月17日 12:55 pm, Benjamin Root wrote: > Then convert them to date objects?
