Plotly chart not showing in Jupyter notebook
PythonJupyter NotebookPlotlyJupyterJupyter LabPython Problem Overview
I have been trying to solve this issue for hours. I followed the steps on the Plotly website and the chart still doesn't show in the notebook.
This is my code for the plot:
colorway = ['#f3cec9', '#e7a4b6', '#cd7eaf', '#a262a9', '#6f4d96', '#3d3b72', '#182844']
data = [
go.Scatter(
x = immigration.columns,
y = immigration.loc[state],
name=state) for state in immigration.index]
layout = go.Layout(
title='Immigration',
yaxis=dict(title='Immigration %'),
xaxis=dict(title='Years'),
colorway=colorway,
font=dict(family='Courier New, monospace', size=18, color='#7f7f7f')
)
fig = go.Figure(data=data, layout=layout)
iplot(fig)
And this is everything I have imported into my notebook:
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import plotly.plotly as py
import plotly.graph_objs as go
from plotly.offline import init_notebook_mode, iplot
init_notebook_mode(connected=True)
Python Solutions
Solution 1 - Python
You need to change init_notebook_mode
call, if you want to work in offline mode.
Such that:
# Import the necessaries libraries
import plotly.offline as pyo
import plotly.graph_objs as go
# Set notebook mode to work in offline
pyo.init_notebook_mode()
# Create traces
trace0 = go.Scatter(
x=[1, 2, 3, 4],
y=[10, 15, 13, 17]
)
trace1 = go.Scatter(
x=[1, 2, 3, 4],
y=[16, 5, 11, 9]
)
# Fill out data with our traces
data = [trace0, trace1]
# Plot it and save as basic-line.html
pyo.iplot(data, filename = 'basic-line')
Output should be shown in your jupyter notebook:
Solution 2 - Python
In case you want to use Jupyter lab, you will have to install the plotly jupyterlab extension: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension.

See the new link: https://www.npmjs.com/package/@jupyterlab/plotly-extension

Simple solution: jupyter labextension install jupyterlab-plotly
Restart Jupyter Lab after installing the extension.
Solution 3 - Python
To use a plotly version below 5.0 in Jupyter Lab make sure you have ipywidgets and plotly installed and then run the following:
jupyter labextension install jupyterlab-plotly
OPTIONAL: Jupyter widgets extension:
jupyter labextension install @jupyter-widgets/jupyterlab-manager plotlywidget
And here's the troubleshooting guide for plotly with Jupyter Lab.
As of Plotly version 5.0, I am able to create a new conda environment with Python 3.9 and then pip install plotly jupyterlab
, and run Jupyter Lab and render plots without any other package or extension installs.
Solution 4 - Python
Being new to Plotly, I had the same issue. I tried all of the above things but still got blank graph. Turns out, only installing the jupyterlab extensions is enough, but you need to shutdown and restart the jupyterlab itself. Just restarting the kernel didn't help.
Solution 5 - Python
Assuming you are using JupyterLab, accordingly to Plotly Troubleshooting
> In order to use plotly in JupyterLab, you must have the extensions
> installed as detailed in the Getting Started guide. There are two
> extensions: jupyterlab-plotly
for rendering figures with fig.show()
> and plotlywidget
for the FigureWidget
.
Assuming that you have installed all the libraries correctly (make sure you have ipywidgets
and nodejs
installed) and assuming one is using conda
, access conda prompt
for the environment one is working (the "Server" environment).
List the labs' extensions with
jupyter labextension list
In my case I got
JupyterLab v2.2.9
No installed extensions
Then I will need to install the extensions jupyterlab-plotly
(the library nodejs
will be required now)
jupyter labextension install jupyterlab-plotly@4.14.3
and plotlywidget
[optional]
jupyter labextension install @jupyter-widgets/jupyterlab-manager plotlywidget@4.14.1
Now you'll be able to visualize your plots.
Note
> If you use JupyterLab with multiple python environments, the > extensions must be installed in the "server" environment, and the > plotly python library must be installed in each "processing" > environment that you intend to use.
Solution 6 - Python
Those having trouble (even after installing extension) may try changing renderer. It worked for me on JupyterLab on Chrome.
Note that this will create a iframe figure directory not pure html file.
If using jupyterlab install JupyterLab extension
jupyter labextension install jupyterlab-plotly
Add this line before py.iplot or fig.show()
import plotly.io as pio
pio.renderers.default = 'iframe'
