title: Seaborn: distplot() with relative frequency
body: <p>I am trying to make some histograms in Seaborn for a research project. I would like the y-axis to relative frequency and for the x-axis to run from -180 to 180.
  Here is the code I have for one of my histograms:</p>
  
  <pre><code>import pandas as pd
  from matplotlib import pyplot as plt
  %matplotlib inline
  import seaborn as sns
  
  df = pd.read_csv('sample.csv', index_col=0)
  
  x = df.Angle
  sns.distplot(x, kde=False);
  </code></pre>
  
  <p>This outputs:
  <a href="https://i.stack.imgur.com/wu2mj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wu2mj.png" alt="seaborn frequency plot"></a></p>
  
  <p>I can't figure out how to convert the output to a frequency instead of a count. I've tried a number of different types of graphs to get frequency output, but to no avail. I have also come across this question which appears to be asking for <a href="https://stackoverflow.com/questions/33179122/seaborn-countplot-with-frequencies">countplot with frequencies</a> (but with another function.) I've tried using it as a guide but have failed. Any help would be greatly appreciated. I'm very new to this software and to Python as well.</p>
  
  <p>My data looks like the following and can be downloaded:
