x-refs

playing with labeled cells, embed, figure ...

trying with cells that produce:

• a 2d plot

• a pandas df

• a folium map

import numpy as np
import matplotlib.pyplot as plt

the source cell¶

we put a label the-labeled-plot on the following code cell

X = np.linspace(0, 2*np.pi)
Y = np.sin(X)

plt.figure()
plt.plot(X, Y);

The history saving thread hit an unexpected error (OperationalError('attempt to write a readonly database')).History will not be written to the database.

referencing the-labeled-plot¶

WITHOUT -- the exclamation mark¶

we write this [some visible text](#the-labeled-plot) some visible text

WITH -- an exclamation mark¶

we write this ![](#the-labeled-plot) (text in brackets doesn’t seem to be used)

matplotlib output¶

EMBED instead¶

now we use an embed directive - with a sharp # in front of the label

matplotlib output¶

FIGURE instead¶

now we use an figure directive - same thing, with a sharp # in front of the label

import seaborn as sns

titanic = sns.load_dataset("titanic")
titanic.head(2)

hover on this text to view the dataframe

import folium

the source cell¶

we put a label the-labeled-map on the following code cell

CENTER = 48.856542, 2.347614

# prune-cell

# on purpose a little smaller so we can more easily scroll 
def paris_map():
    return folium.Map(
        location=CENTER,
        zoom_start=13,
        # width='80%',
    )

paris_map()

referencing the map¶

this should show a map ?

referencing a hidden notebook¶
