ipywidgets don't seem to work on mybinder.org

[sg-s]

I have a python notebook [here])https://github.com/sg-s/rent-or-buy) that uses ipywidgets to enable interactivity.

However, on binder, the notebook renders without any errors, but the widgets seem "dead", and don't update plots.

Link to binder live notebook

• Is this expected behaviour?
• Can ipywidgets be used on binder?
• If not, what tools exist for interactivity on binder?

Thanks in advance

Hi!

widgets should work. If I launch https://github.com/binder-examples/requirements I can paste the following simple widget code:

import ipywidgets as widgets
widgets.IntSlider()

and get a slider that slides.

TL;DR: It should just work.

As a general comment: for support questions like this (discussions that aren't about making changes to the binderhub repo itself) it is better to create a thread on http://discourse.jupyter.org/ as it has more readers and is indexed by google so future readers will have an easier time finding similar issues/solutions.

If I replace %matplotlib notebook with %matplotlib inline in your notebook I get a plot in your notebook. So maybe this is a question of how to configure matplotlib (figures)?

HI, I should have been more clear.

The sliders do render in my notebook, as do the plots. But moving the sliders doesn't update the plot.

OK, I fixed the problem as I was missing a plt.show()

thanks for your help!
