title: Graphing date vs time on plotly
body: <p>I have several data sets I would like to plot with dates as X axis and times as Y axis. I am working in Jupyter Notebook.</p>
  
  <pre><code>from datetime import date, time
  from plotly import offline as py
  from plotly.graph_objs import Scatter, Data
  py.init_notebook_mode(connected=True)
  
  meetings = Scatter(
      x=[date(2017, 1, 1), date(2017, 1, 3), date(2017, 1, 3)],
      y=[time(8, 0, 0), time(12, 0, 0), time(16, 0, 0)],
      text=['work meeting 1', 'work meeting 1', 'work meeting 1'],
      mode='markers'
  )
  
  workouts = Scatter(
      x=[date(2017, 1, 1), date(2017, 1, 2), date(2017, 1, 2)],
      y=[time(7, 30, 0), time(14, 30, 0), time(17, 0, 0)],
      text=['workout 1', 'workout 2', 'workout 3'],
      mode='markers'
  )
  
  data = Data([meetings, workouts])
  py.iplot(data)
  </code></pre>
  
  <p>The result I get is this:
  <a href="https://i.stack.imgur.com/2910u.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/2910u.png" alt="result"></a>
  The X axis includes time as well, and the Y axis goes in order of inserted data, not from bottom to top. Nothing I've tried with modifying the range/domain has fixed this.
  From what I've seen on the  <a href="http://help.plot.ly/date-format-and-time-series/" rel="nofollow noreferrer">help page</a> time objects aren't supported.
  Is there any way to make this type of plot work?</p>
