Say I have a callback function that changes a Graph’s figure. Is it possible to decouple that callback from that Graph’s figure later, and even reassign another function as the callback to change Graph figure? Thanks.
What kind of callback are you talking about? The
on_unhover callback registration functions all include an optional
append argument. When
append=False (the default) each time a callback function is registered it replaces all previously registered callbacks. If
append=True then the new callback is added to the list of existing callbacks. And you can remove a callback by calling, for example,
Hope that helps!
Hi @jmmease, can I do what you described in the Python Dash API? The ability to do what you just described is exactly what I need. However, looking at the
dash.py source on Github, I don’t see a way to set an
append parameter on
In Dash the callback definitions are defined in the application before the server starts and it’s not possible (at least not as far as I know) to modify them after the fact. If you want to talk about how to accomplish a particular workflow using Dash, I’d recommend describing a simple example of what you’re trying to do in a new forum post in the Dash category.
Thanks @jmmease ! At least it’s clear to me now that this isn’t possible for now in Dash. I’ll describe what I ultimately want to do in a separate post when I get the chance.
