Burn-in for plots other than traceplot

Is there a “statistical” reason why are burn-ins not implemented for most kind of plots except for traceplot and autocorrelation? Or is it just because they are simply not implemented yet?

Actually I would argue that burn-ins should not be implemented in any plot - it should always up to the user to pass trace[500:] to plotting function.

Ah that’s a nice trick, I couldn’t find it in the doc. Thanks
