There are two parts to this task:
- Make the plot container interactive, allowing resizes
- Pass the new size to the underlying Bokeh plot
To solve (1), you can either write something yourself or use one of the numerous JS libraries that already do that. For example, https://interactjs.io/
To solve (2), you have to get a handle to the correct instance of the
models/plots/plot/Plot model and just set
height to the new values. In order to get the instance, you can either specify a model ID when you create the plot and then just call
Bokeh.documents.get_model_by_id(model_id) (assuming you have just one document on the page) or you can store the model when you embed the document (feasibility of this option depends on how you actually embed the document into your web page).
