Hi,

Can you explain little bit more that is your code doing?
_getJsCode() function returns just JSON code, which is inserted into HTML page.
There is no SVG code until JSROOT rendering is performed.

Hi,

It converts drawableObject to svg and attaches it to the object passed to IPython.display.display.

Indeed, so I get nothing in place of plot when I convert a notebook to LaTeX.

Hi,

To make nbconvert working one has to invoke JSROOT before.
I am not sure how this can be implemented - normally JSROOT executed in context of the browser.

Sergey

That’s why I propose to attach a statically SVG PDF-prerendered plot so that a user gets it when uses nbconvert.

I am also looking for a solution to export notebooks with plots when jsroot is on. the proposal of @berserker which goes beyond my knowledge on how to implement, are there any other way?

Thanks a lot
Stefano
