Test jupyterlab-plotly, jupyterlab-dash and jupyter-matplotlib

[ca-scribner]

Do they work? jupyter-matplotlib gave me these errors:

matplotlib notebook
matplotlib.pyplot as plt
plt.plot([[0,0], [1,1]], label='line')
plt.show()

Make sure they do, and while doing that build demo notebooks that can be added to jupyter-notebooks repo so we have both test cases and demos for users

[ca-scribner]

the matplotlib extension is also installed twice (once by us, and once upstream). Remove the second one?

jupyterlab-dash has been deprecated in place of jupyter-dash. Update to the newer one

[Jose-Matsuda]

Confirming that I get the "IPython is not defined" with %matplotlib notebook
From what I understand we should use %matplotlib widget instead. See matplotlib jupyter-notebooks or the matplotlib ipympl github proj

So your snippet of code became

%matplotlib widget 
import matplotlib.pyplot as plt
import numpy as np
plt.plot([[0,0], [1,1]], label='line')
plt.show()

Removed the extra installation of jupyter-matplotlib in the minimal-notebook cpu and tested in the Python 3 notebook successfully. Graph was interact-able (moused over graph and X+Y co-ords appeared below as opposed to a normal graph created by just running the code sans %matplotlib widget)
Saved+downloaded the notebook containing the code above and the resulting graph.

Still TODO:

• Update jupyterlab-dash to jupyter-dash.
• Test jupyter-dash
• Test jupyter-plotly

[Jose-Matsuda]

jupyter-plotly works with some examples from plotly.com basic charts the following is from bar charts

import plotly.express as px
data_canada = px.data.gapminder().query("country == 'Canada'")
fig = px.bar(data_canada, x='year', y='pop')
fig.show()

jupyterlab-dash
Example(s) from the jupyterlab-dash git page do not produce expected output.
Does not appear in installed extensions.

TLDR;
jupyter-matplotlib: works, removed the duplicate installation still worked, have the ipynb file.
jupyter-plotly: works, have the ipynb file.
jupyterlab-dash: no bueno
