`ipympl`#

Since the Jupyter widget ecosystem is developing too quickly, the Matplotlib developers have decided to outsource the support to a separate module: ipympl or jupyter-matplotlib.

Installation#

ipympl is installed in both the kernel and the Jupyter environment

pipenv install ipympl
Installing ipympl…
Adding ipympl to Pipfile's [packages]…
✔ Installation Succeeded

Then you can activate the Jupyter backend in notebooks by using the following Matplotlib-Magic:

%matplotlib widget

Examples#

Simple Matplotlib interaction#

[2]:

import matplotlib.pyplot as plt
import numpy as np

plt.figure(1)
plt.plot(np.sin(np.linspace(0, 20, 100)))
plt.show()

3D plot: subplot3d_demo.py #

[3]:

from mpl_toolkits.mplot3d import axes3d

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Grab some test data.
X, Y, Z = axes3d.get_test_data(0.05)

# Plot a basic wireframe.
ax.plot_wireframe(X, Y, Z, rstride=10, cstride=10)

fig.canvas.layout.max_width = '800px'

plt.show()

More complex example from the Matplotlib gallery #

[4]:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(0)

n_bins = 10
x = np.random.randn(1000, 3)

fig, axes = plt.subplots(nrows=2, ncols=2)
ax0, ax1, ax2, ax3 = axes.flatten()

colors = ['red', 'tan', 'lime']
ax0.hist(x, n_bins, density=1, histtype='bar', color=colors, label=colors)
ax0.legend(prop={'size': 10})
ax0.set_title('bars with legend')

ax1.hist(x, n_bins, density=1, histtype='bar', stacked=True)
ax1.set_title('stacked bar')

ax2.hist(x, n_bins, histtype='step', stacked=True, fill=False)
ax2.set_title('stack step (unfilled)')

# Make a multiple-histogram of data-sets with different length.
x_multi = [np.random.randn(n) for n in [10000, 5000, 2000]]
ax3.hist(x_multi, n_bins, histtype='bar')
ax3.set_title('different sample sizes')

fig.tight_layout()
plt.show()
