Two issues in assignment 4

[Q-Quan]

1. When using the %matplotlib notebook magic, I don't get interactive graphs. Instead, in PyCharm, the graphs stay empty. And in Jupyter (in-browser), the graphs and control buttons appear, but I still cannot interact with them (click actions don't do anything).
2. Running the_box.show_tradeoff() displays two identical graphs instead of just one.

Python 3.11.3 / PyCharm 2023.1 / macOS 13.3.1

1. why would you expect interactive graphs?
2. do you follow up show_tradeoff with plt.show()?

2. do you follow up show_tradeoff with plt.show()?

This he doesn't, I suspect the function both returns a figure / axes object, and calls plt.show().

Edit: Can't reproduce it though. Might be a Mac thing (I'm running Windows).

@Q-Quan a full Jupyter notebook in which this happens might help.

1. When using the %matplotlib notebook magic, I don't get interactive graphs.

I do, should look something like this:

[quaquel]

show_tradeoff only returns a figure and plt.show is not called within the function. If you don't follow up with plt.show(), at least on mac, this results in showing the figure twice.

[Q-Quan]

1. As in Ewout's screenshot, I would expect a figure with buttons. With the notebook opened in PyCharm, no figure appears at all; in an in-browser Jupyter notebook, these buttons would not do anything, as far as I could discover.
2. It happens as you say, @quaquel. Is this intended behaviour, then?

[quaquel]

1. No idea, I don't use interactive matpltolib figures.
2. this is what happens in jupyter when you create a figure but don't call plot.
