title: Plotly: How to change the background color of each subplot?
body: <p>I am trying to create different subplot and I want for each subplot to have a different background color. I'm using plotly and it makes the thing a little bit more difficult. Any idea? I think the equivalent in matplot is face_color or something like this.</p>
  
  <pre><code>fig = make_subplots(rows=1, cols=2)
  
  fig.add_trace(
      go.Scatter(
          x=list(range(sample_points)),
          y=data_gx.iloc[scene],
          name='X-axis',
          line=dict(color='green', width=2)
      ),
      row=1, col=1
  )
  
  fig.add_trace(
      go.Scatter(
          x=list(range(sample_points)),
          y=data_ax.iloc[scene],
          name='X-axis',
          line=dict(color='green', width=2)
      ),
      row=1, col=2
  )
  </code></pre>
