title: Plot a histogram through all the columns
body: <p>I have a data that has several columns in it.</p>
  
  <pre><code>Country    Weight    # of food/day  ....
  ---------------------------------------------
  USA         180         4
  China       190         12
  USA         150         2
  Canada      300         10
  </code></pre>
  
  <p>I want to create (separate) histogram for each of the columns such that histogram_1 shows the distribution of 'Country', histogram_2 shows the distribution of 'Weight', etc.</p>
  
  <p>I'm currently using panda to upload and manipulate the data.</p>
  
  <p>Is the easy way to do this is by doing like this?</p>
  
  <pre><code>for column in df:
      plt.hist(column)
      plt.show()
  </code></pre>
  
  <p>Please forgive me if my idea sounds so stupid.</p>
  
  <p>Any help would be highly appreciated, thanks!</p>
