title: Extra lane in heat map (pandas)
body: <p>Here is my <a href="https://www.dropbox.com/s/0ymrbo7v9vxpjhu/extra_line.csv?dl=0" rel="nofollow">file</a></p>
  
  <p>I plot heat map from it using the following code:</p>
  
  <pre><code>import pandas as pd
  import matplotlib.pyplot as plt
  
  new = pd.read_csv(r'path_to_file')
  full_list=new.columns.values
  new = new[full_list[1:]]
  plt.pcolor(new, cmap='Blues')
  plt.show()
  </code></pre>
  
  <p>File has only 11 rows of values, but for some reason 12 rows show up. Do you know what is wrong?
  Here is how output looks for me:
