Pairplot does not actually accept grid/axis argument

See original GitHub issue

This example I would expect to have two different scatter plots on each axis, but it only plots the first one:

import arviz as az

centered = az.load_arviz_data('centered')

axes, gridspec = az.plot_pair(
    centered.posterior, 
    var_names=['theta', 'mu'], 
    coords={'school': ['Choate', 'Deerfield']}, 
    plot_kwargs={'c': 'C0'})

az.plot_pair(
    centered.prior, 
    var_names=['theta', 'mu'], 
    coords={'school': ['Choate', 'Deerfield']}, 
    ax=axes, 
    gs=gridspec, 
    plot_kwargs={'c': 'C1'})

I think I’ll quickly fix this, settling for your first option above (remove those arguments). Three appears to be dangerous (as it will be hard to distinguish cases where axes are deleted etc, and that might lead to fairly hard-to-debug bugs), two might be added in the future, but essentially will also come down to first implementing the first option as far as I can tell.

Thanks for checking – I just reran the initial code, and it now works with a little tweak:

centered = az.load_arviz_data('centered_eight')

axes = az.plot_pair(
    centered.posterior, 
    var_names=['theta', 'mu'], 
    coords={'school': ['Choate', 'Deerfield']}, 
    plot_kwargs={'c': 'C0'}, figsize=(15, 8))

az.plot_pair(
    centered.prior, 
    var_names=['theta', 'mu'], 
    coords={'school': ['Choate', 'Deerfield']}, 
    ax=axes, 
    plot_kwargs={'c': 'C1', 'alpha': 0.7})
