title: How to replace pandas plot xticks with days?
body: <p>I've got a pandas hist plot like shown below. As you can see the xticks are currently set to 0-6 (Sunday - Saturday). I'd like to replace the tick label to the actual days so the days are showing instead of numbers.
  0 - Sunday
  1 - Monday
  2 - Tuesday
  3 - Wednesday
  .
  .</p>
  <pre><code>ax_by_day = df['Day Of Week'].hist(bins=7, alpha=0.5, figsize=(10,6), edgecolor='black')
  ax_by_day.set_xticks(list(range(0,7,1)))
  ax_by_day.set_xlabel('Day')
  ax_by_day.set_ylabel('No. of Processes Executed')
  </code></pre>
  <p>I believe there's a way to map the xticks to new labels but surprisingly I'm unable to find details. Thanks in advance.</p>
