title: Plotting two columns of dataFrame in seaborn
body: <p>I'm trying to create a bar chart in seaborn that displays values for two variables(Weight, Variance) for each row (Factor) in my data frame. Here is what my data looks like:</p>
  
  <pre><code>    Factor    Weight  Variance
      Growth    10%      0.15
      Value     20%      0.35
  </code></pre>
  
  <p>Here is my code:</p>
  
  <pre><code>    fig=plt.figure(figsize=(10,10))
      ax1=fig.add_subplot(221)
      sns.barplot(x=df.index, y=df[['Weight', 'Variance']], ax=ax1)
  </code></pre>
  
  <p>The above throws back an error every time that I can't debug. What I am trying to achieve is have one plot, that shows two colored bars for each Factor; weight in one color (ex: red) and variance in another color (ex: blue). </p>
  
  <p>Anyone have suggestions or potential workarounds? </p>
  
  <p>Thanks</p>
