newer nb/nbviewer does not display plot from R kernel (but nb 3.0 does) about notebook HOT 8 CLOSED

I see the plot when I open that file in the live notebook dev version.

I wonder if some of the nbconvert code assumes that text/plain is always present? The Python kernel will always offer a plain text repr, and I think we expect that to always exist, though we may not have written that down.

Actually, that can't be it, because you can use e.g. display_png() in IPython and that displays without a text/plain format.

I think this is an nbconvert issue. I can reproduce it on master by doing ipython nbconvert --to html plot_not_visible.ipynb. There's no error message.

Aha, I think I see it. application/pdf is given a higher priority in the HTML output than SVG or PNG for some reason, so it tries to display that, but there's no block in the template to display pdf data. I think reordering the display priority should fix it.

See jupyter/nbconvert#5

Ok, that means the nbviewer one is dealt with (damn, I was actually writing the issue in that project but switched here before hitting submit). Thanks!

Also thanks for confirming that it is visible in the dev notebook and it's therefore not the formatting of the uuencoded data. Back to step one... :-/

Update: it seems that I misunderstood "print preview" and the Jupyter "File -> Print Preview" uses nbconvert in the background -> so it seems that this is both fixed by jupyter/nbconvert#5.

Thanks a lot!

Yep, our own 'print preview' menu item uses nbconvert to convert to static HTML.
