Download button -> pdf instead of png?

[srosenzweig09]

Problem

I love the toolbar that accompanies figures, especially since I can click to save them directly to my local drive (I work remotely). Currently, the download button defaults to .png file type. I would love the option to set this button to download as .pdf file types. Is this possible? Thanks!

Is this for ipympl specifically? I see that you opened matplotlib/ipympl#339 already. If this is only for ipympl, then please close this issue in ipywidgets :)

Hi, so I'm not sure, honestly. Here is the procedure:

%matplotlib widget
import Matplotlib.pyplot as plt

fig, ax = plt.subplots()
** plot something **

A figure appears with a toolbar, as shown here:

Clicking on the "Save" button downloads to my local drive. I'm not sure whether this is an ipympl or matplotlib mechanism... I just figured I'd post to a couple of places and see if anyone has an answer.

This is more likely to be an issue related to ipympl, or maybe matplotlib. But I believe this is unrelated to ipywidgets.

I answered to the ipympl one, let's continue to chat there :)
