Using a Cell Tag to Select a Thumbnail

You can select any code cell (with appropriate output) by tagging it with the nbsphinx-thumbnail tag.

If there are multiple outputs in the selected cell, the last one is used. See Choosing from Multiple Outputs for how to select a specific output. If you want to show a tooltip, have a look at Using Cell Metadata to Select a Thumbnail.

[1]:
import matplotlib.pyplot as plt

The following cell has the nbsphinx-thumbnail tag, which will take precedence over the default of the last image in the notebook:

[2]:
fig, ax = plt.subplots(figsize=[6, 3])
ax.plot([4, 9, 7, 20, 6, 33, 13, 23, 16, 62, 8])
[2]:
[<matplotlib.lines.Line2D at 0x7f86450e8c50>]

Although the next cell has an image, it won’t be used as the thumbnail, due to the tag on the one above.

[3]:
fig, ax = plt.subplots(figsize=[6, 3])
ax.scatter(range(10), [0, 8, 9, 1, -8, -10, -3, 7, 10, 4])
