Plotly notebook mode with google colaboratory

simply pass "colab" as the value for the parameter renderer in fig.show(renderer="colab")

example :

import plotly.graph_objects as go
fig = go.Figure(
    data=[go.Bar(y=[2, 1, 3])],
    layout_title_text="A Figure Displayed with the 'colab' Renderer"
)
fig.show(renderer="colab")

plotly version 4.x

As of version 4, plotly renderers know about Colab, so the following is sufficient to display a figure in both Colab and Jupyter (and other notebooks like Kaggle, Azure, nteract):

import plotly.graph_objects as go
fig = go.Figure( go.Scatter(x=[1,2,3], y=[1,3,2] ) )
fig.show()

plotly version 3.x

Here's an example showing the use of Plotly in Colab. (Plotly requires custom initialization.)

You need to define this function:

def configure_plotly_browser_state():
  import IPython
  display(IPython.core.display.HTML('''
        <script src="/static/components/requirejs/require.js"></script>
        <script>
          requirejs.config({
            paths: {
              base: '/static/base',
              plotly: 'https://cdn.plot.ly/plotly-latest.min.js?noext',
            },
          });
        </script>
        '''))

And call it in each offline plotting cell:

configure_plotly_browser_state()
