From the plot.ly website for histogram https://plot.ly/python/histograms/
we have the following snippet:

import plotly.plotly as py

import plotly.graph_objs as go



import numpy as np

x = np.random.randn(500)

data = [go.Histogram(x=x)]

py.iplot(data, filename='basic histogram')

But running this gives us complaints that it is not being run on their hosted service:

Aw, snap! We didn't get a username with your request.

PlotlyError: Because you didn't supply a 'file_id' in the call, we're assuming you're trying to snag a figure from a url. You supplied the url, '', we expected it to start with 'https://plot.ly'.

Run help on this function for more information.

So then how is plot.ly to be used from a standard ipython REPL?

Since plotly 3 you can work in Jupyter Notebooks using only plotly.graph_objs though FigureWidget, if you need to explicitly show a plot you can use ipython's display as with any other widget:

from IPython import display

from plotly import graph_objs as go    

import numpy as np



x = np.random.randn(500)

figure = go.FigureWidget()

figure.add_trace(go.Histogram(x=x))

display.display(figure)

Two things are required: first off make sure to have a recent version of plotly: I had had 1.8.3 and after upgrading to 2.7.0 things are looking much better.

In addition: from a comment by @cody - I looked more carefully at the offline mode at http:// plot.ly/python/offline . It is not immediately apparent which way to plot : but we need the following magic to be run:

init_notebook_mode(connected=True)

So the code snippet is now:

from plotly import __version__

from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot

import plotly.plotly as py

import plotly.graph_objs as go

import pandas as pd

import requests

bike = pd.read_json('/shared/bikeRental.json',lines=True)

#bike.createOrReplaceTempView('bike')

#x=sqldf('select Duration from bikePd where Duration < 7200')

x=sqldf('select Duration from bike where Duration < 7200')

init_notebook_mode(connected=True)

hist = [go.Histogram(x=x['Duration'].values)]

plot(hist,filename='/shared/bikeRides')

Which produces:
