The parameter values looks repeating in the chains

[WeakDog]

Hello,

I'm now using the emcee and just found that the chains look weird where the parameter values appear to be repeated in the chains. I attach the figure showing the parameters as a function of the steps in the chain below. I was wondering whether this is reasonable or not. Thanks!

This looks like a plotting issue to me. Take a look at the docs for an example of how to plot your traces: e.g. https://emcee.readthedocs.io/en/stable/tutorials/line/#marginalization-uncertainty-estimation

Many thanks for your help!
