Hi Thales,
I've been thinking about this and the best solution I can think of would be
to save the figures to disk, and explicitly invoke them with the
traditional
\begin{figure}
…
\caption{ \label{fig:your-label} your caption.}}
\end{figure}
I think should be able to do this with a simple markdown LaTeX invocation,
but it may require using a nbconvert raw cell.
Note: this won't look good in the browser itself, but it will work on
export.
Other than that, this is something that we've been talking about how to
implement for a while. The current thought is that we might want to create
a new IPython Figure class that allows you to programmatically set this
kind of metadata so that it is attached directly to your outputs.
In terms of equations, you should be able to specify a label inside the
equation \begin{equation} \label{eq:your-label} … \end{equation}. However,
specifying a ref in line is somewhat more challenging. The problem is that
MathJax (what we use in the notebook browser to display maths) only
(ostensibly) surfaces math mode via its commands. As a result of that,
everything that is captured by LaTeX that isn't a `\begin{blah}…\end{blah}`
command is automatically assumed to be in math mode, and I do not believe
that `\ref` (or better `\autoref` since we use the `hyperref` package in
the default template) work inside math mode. I'll try to think about a
better way to solve this…maybe using something like the data-attribute
trick we use for citations (e.g., <a data-cite="pacer2015">(Pacer,
2015)</a>), because this should be possible.
Cheers,
M
