FigureWidget doesn't update in Jupyter Notebook

[ubershmekel]

This snippet in a Python cell produces a chart, but the chart does not update to get the new title and new data.

import plotly.graph_objs as go
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot

init_notebook_mode()
data = [go.Bar(
            x=['giraffes', 'orangutans', 'monkeys'],
            y=[20, 14, 23]
    )]
layout = {'yaxis': {'range': [0, 25]}}
fig = go.FigureWidget(data, layout)
iplot(fig)

# The following code is ignored.
fig.data[0].y = (5,10,1)
fig.layout.title = "New title"

Hi @ubershmekel ,

For the visual display of the FigureWidget to update you need to allow it to display itself as an ipywidget by making the fig variable the last statement in a notebook cell. In particular, you can't use iplot. For example:

import plotly.graph_objs as go

data = [go.Bar(
            x=['giraffes', 'orangutans', 'monkeys'],
            y=[20, 14, 23]
    )]
layout = {'yaxis': {'range': [0, 25]}}
fig = go.FigureWidget(data, layout)
fig

# The following code will update the plot above
fig.data[0].y = (5,10,1)
fig.layout.title = "New title"

Does that work for you?

[ubershmekel]

@jonmmease When I do that - nothing is displayed after the cell completes.

[jonmmease]

Ok, then it sounds like there is some kind if installation problem with respect to the FigureWidget.

Are you using the classic Jupyter Notebook or JupyterLab?

If classic, please include the output of

jupyter nbextension list

if JupyterLab, please include the output of

jupyter labextension list

What version of ipywidgets is installed?

Do you see any errors/messages in the browser console? (https://developers.google.com/web/tools/chrome-devtools/console/)

[ubershmekel]

There are errors in the console...

[jonmmease]

Thanks for adding the additional info.

When you see these errors, are you running the classic notebook or jupyterlab?

What version of ipywidgets do you have installed?

Also, since it looks like you're using conda. Could you double check that you don't have the plotly or ipywidgets packages installed using both conda and pip? (You can check by running pip list and conda list).

[ubershmekel]

You are using Jupyter notebook.
The version of the notebook server is: 5.7.4

I believe that means classic notebook.

Indeed there are duplicate ipywidgets and plotly between the pip and conda.

ipywidgets                         7.4.2     
ipywidgets                7.4.2                    py37_0  
plotly                    3.5.0                     <pip>
plotly                             3.5.0     

[jonmmease]

I believe that means classic notebook.

The server between the two is actually identical. The difference is whether you run jupyter notebook or jupyter lab from the command line to start up the server.

Indeed there are duplicate ipywidgets and plotly between the pip and conda.

Alright, let's try this

$ pip uninstall ipywidgets
$ pip uninstall plotly
$ conda uninstall ipywidgets
$ conda uninstall plotly

$ conda install -c plotly plotly=3.5.0
$ conda install "notebook>=5.3" "ipywidgets>=7.2"

If that doesn't help, try uninstall and reinstalling the notebook extension

$ jupyter nbextension uninstall --py --sys-prefix widgetsnbextension
$ jupyter nbextension uninstall --py --sys-prefix plotlywidget
$ jupyter nbextension install --py --sys-prefix widgetsnbextension
$ jupyter nbextension install --py --sys-prefix plotlywidget
$ jupyter nbextension enable --py --sys-prefix widgetsnbextension
$ jupyter nbextension enable --py --sys-prefix plotlywidget

Partial success!!! (working in jupyter lab but not in jupyter notebook)
When I follow the below steps, it started working only in jupyter lab but not in jypyter notebook.
In my jupyter notebook "Nbextensions" tab, both ploltywidget and jupyter-js-widgets extensions are disabled and says "possibly incompatible". I don't really understand why these are incompatible even though validation says it's OK. (Image attached).

Nbextension list in Jupyter:

Labextension list in Jupyter lab

steps followed:

jupyter nbextension uninstall --py --sys-prefix widgetsnbextension
jupyter nbextension uninstall --py --sys-prefix plotlywidget
jupyter nbextension install --py --sys-prefix widgetsnbextension
jupyter nbextension install --py --sys-prefix plotlywidget
jupyter nbextension enable --py --sys-prefix widgetsnbextension
jupyter nbextension enable --py --sys-prefix plotlywidget

Please help me fix it in jupyter notebook as well.

Additionally, I noticed that plotlywidget and jupyter-js-widget extensions are in an entirely different folder compared to deafult nbextension folder. Is this causing the problem? If yes, could you please help me on how to fix ? What files (file path) should I copy from one location to another location?

Details: I don't have conflicting packages (for any of them listed below) in conda list and pip list.

Python: 3.7 (64-bit)
Plotly:                                                       3.7.0
ipywidgets                                                7.4.2

Hi @ubershmekel ,

For the visual display of the FigureWidget to update you need to allow it to display itself as an ipywidget by making the fig variable the last statement in a notebook cell. In particular, you can't use iplot. For example:

import plotly.graph_objs as go

data = [go.Bar(
            x=['giraffes', 'orangutans', 'monkeys'],
            y=[20, 14, 23]
    )]
layout = {'yaxis': {'range': [0, 25]}}
fig = go.FigureWidget(data, layout)
fig

# The following code will update the plot above
fig.data[0].y = (5,10,1)
fig.layout.title = "New title"

Does that work for you?

for me it worked like a charm, thanks a lot!
