title: Multiple barplot does not work for dataframe
body: <p>This is my data, i want to make a multiple barplot for the cluster that holds the columns so the bars would be 4 (represents panicattacks ,compulsivebehavior ,depression and anxiety)  and will repeat for each cluster (total is 6).</p>
  
  <pre><code>            panicattacks    compulsivebehavior   depression anxiety
  cluster             
  0                2.0               0.0                2.0   2.0
  1                1.0               1.0                2.0   2.0
  2                0.0               0.0                0.0   0.0
  3                3.0               3.0                3.0   3.0
  4                1.0               1.0                7.0   7.0
  5                1.0               0.0                6.0   7.0

  <pre><code>ax = plt.subplot(111)
  for i,row in enumerate(unemployed.values):
      ax.bar(unemployed.index[i], unemployed['panicattacks'], width=0.2, color='b', align='center')
      ax.bar(unemployed.index[i], unemployed['compulsivebehavior'], width=0.2, color='r', align='center')
      ax.bar(unemployed.index[i], unemployed['depression'], width=0.2, color='g', align='center')
      ax.bar(unemployed.index[i], unemployed['anxiety'], width=0.2, color='y', align='center')
