title: Plotly - how to replicate the same histogram in a single plot
body: <p>How to have this same graph on another row below?</p>
  
  <pre><code>import plotly.offline as py
  import plotly.graph_objs as go
  import numpy as np
  
  x0 = np.random.normal(loc=0, scale=1, size=1000)
  x1 = np.random.normal(loc=0.1, scale=0.2, size=100)
  
  trace0 = go.Histogram(
      x=x0
  )
  trace1 = go.Histogram(
      x=x1
  )
  data = [trace0, trace1]
  
  
  layout = go.Layout(barmode='stack')
  fig = go.Figure(data=data, layout=layout)
  
  py.plot(fig, filename='stacked histogram')
  </code></pre>
  
  <p>I want to get from this, a single histogram in one plot:</p>
