title: Add more data to barplot
body: <p>There are a dataframe :</p>
  <pre><code>{'Date': {0: '2020-06-01',
    1: '2020-06-02',
    2: '2020-06-03',
    3: '2020-06-04',
    4: '2020-06-08'},
   'Started': {0: 1, 1: 1, 2: 3, 3: 2, 4: 2},
   'Ended': {0: 0, 1: 0, 2: 2, 3: 0, 4: 1},
   'conversion': {0: 0.0, 1: 0.0, 2: 0.67, 3: 0.0, 4: 0.5}}
  </code></pre>
  <p>I'm visualizate it by  <code>data2.set_index('Date').plot.bar(figsize = (25, 20))</code> in JupiterNotebook</p>
  <p>But i also need to add data from column 'conversion' under 'date' or maybe over columns. It is not necessary to do it in my way, maybe use seaborn or etc</p>
