title: I want to seperate a column by the numerical values within but it sees it as bool so I cant graph by value
body: <p>So I have a CSV that has one column on latitude. For the northern hemisphere I want the value it to only count all values more than zero, and south less than zero. </p>
  
  <pre><code>north_df = (df.iloc[:,7] &gt; 0)
  
  north_df.head()
  
  south_df = (df.iloc[:,7] &gt; 0)
  
  south_df.head()
  </code></pre>
  
  <p>this code just gives me a true or false statement on wheter it is smaller than zero or not.  However I want to make a scatter plot of that Latitude along with other columns like max temp. Unfortunately when I make a scatter plot the value of the latitudes are either 1 or 0 rather all the latitudes 0 to -60 and 0 to 60  </p>
