Plot KDEs horizontally?

See original GitHub issue

Hey, not sure if there’s an interest in this or if this package is actively maintained? I really like this idea of centralizing MCMC plotting tools.

When doing a traceplot, it can help to link the kernel density/histogram to the trace if the histogram/kdeplot closes over the trace. If seaborn is used for the kernel density, it’s only a keyword argument to flip. I think, if this option would be useful in this package, then it should be possible to use ax.fill_betweenx.

There are a lot of other views I’ve built that might be more useful generally for MCMC that could take arbitrary sample chains.

@dustinvtran Since this wasn’t adopted the name can easily be changed. The focus on MCMC is because Stan and PyMC3 are focused on MCMC and there are a certain set of plots people do over and over.

Maybe we should decide on what code we would like to share. We seem to agree on plotting, but some other things come to mind:

Convergence diagnostics for MCMC
Model comparison metrics (DIC, WAIC etc)
Sampling backends to store traces (this could be quite useful for users as it makes interoperability between our packages trivial).

@dustinvtran Not sure if there are variational analyses that would make sense to share?

In any case, before doing any code changes here, we should update to pymc3’s most recent plotting code.

Closing as this have been addressed. If you think sometimes still needs attention, I would suggest to open a a new issue.
