covariance ellipses

[steven-murray]

Any plans on adding simple covariance ellipses to the plots?

[Samreay]

Can you provide an example figure, Im not sure what you mean

[steven-murray]

Something like this. The ellipses are just 1- and 2- sigma areas of the multivariate normal defined by the covariance of the data. Can be useful for checking how Gaussian the posterior is.

Ah right. Yeah that could be useful, will try to find some time to add that in.

You might have guessed, am doing an issue clean up. There is an add_covariance method now, detailed here: https://samreay.github.io/ChainConsumer/examples/Basics/plot_covariance_and_marker.html that solves this issue (hopefully).
