That’s a good and fair question!
- Architecturally, we are planning to replace all of pymc3’s plotting with arviz for the next release, so most improvements from maintainers have been focused there trying to get to feature parity.
- We aren’t against maintaining pymc3’s plotting library: If you want to put together a pull request that accepts an
axesobject there, it would be happily accepted.
I would guess that by the end of January, arviz is integrated with the master branch of PyMC3 on github, depending on how much time everyone has.
