title: LaTeX pgfplots use strings for barchart label from .csv
body: <p>I'm trying to use data from a .csv file to create a barchart with labels that are non-numeric. I've looked through a few older examples, but they seem large and clunky. I'm hoping there's a better way. Here's what I have so far as a MWE:</p>
  
  <pre><code>\documentclass[11pt]{article}
  \usepackage{pgfplots}
  \pgfplotsset{compat=1.9}
  
  \begin{document}
  \begin{tikzpicture}
  \begin{axis}[xlabel=x axis label,ylabel=y axis label]
  \addplot [ybar] table [symbolic x coords=Month, y=Dozers, col sep=comma] {cnrldata.csv};
  \end{axis}
  \end{tikzpicture} \\
  \end{document}
  </code></pre>
  
  <p>From this I of course get the error: </p>
  
  <pre><code>Package PGF Math Error: Could not parse input 'May 14' as a floating point number, sorry. The unreadable part was near 'May 14'.. ... y=Dozers, col sep=comma] {data.csv};
  </code></pre>
  
  <p>The data in the table looks like this:</p>
  
  <pre><code>Month, Dozers,
  January, 0.85,
  February, 0.7,
  </code></pre>
