Using Cell Metadata to Select a Thumbnail¶

If the nbsphinx-thumbnail cell tag is not enough, you can use cell metadata to specify more options.

The last cell in this notebook has this metadata:

{
    "nbsphinx-thumbnail": {
        "tooltip": "This tooltip message was defined in cell metadata"
    }
}

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.
