title: How to plot 2 different time series data frames without resampling
body: <p>I am trying to plot 2 data frames with different time series. Seems like a simple problem but im just unable to solve it..</p>
  
  <p>Here is a sample data: <strong>df1</strong> is resampled to 30 minutes, but <strong>df2</strong> can't be resampled, it must be used as is..</p>
  
  <p><strong>df1</strong></p>
  
  <pre><code>time                        A   B
  2020-01-10 18:00:00+00:00   8   3
  2020-01-10 18:30:00+00:00   7   6
  2020-01-10 19:00:00+00:00   2   1
  2020-01-10 19:30:00+00:00   4   8
  2020-01-10 20:00:00+00:00   5   4
  2020-01-10 20:30:00+00:00   1   5
  2020-01-10 21:00:00+00:00   6   4
  </code></pre>
  
  <p><strong>df2</strong></p>
  
  <pre><code>time                                C
  2020-01-10 18:50:15.200000+00:00    0.18
  2020-01-10 18:58:15.227000+00:00    0.00
  2020-01-10 19:29:36.519000+00:00    0.54
  2020-01-10 19:50:45.810000+00:00    0.88
  2020-01-10 20:41:27.064000+00:00    0.19
  </code></pre>
  
  <p>Expected result: a unique time-series graph with <strong>df1</strong> values (here 0 to 10, but can change based on the data) on left y-axis, and <strong>df2</strong> values (always between 0 to 1) on the right y-axis, and in the form of a line-plot that looks like a bar plot, like the orange line in the pic:</p>
