pippi

Parse it, plot it. 

A program for operating on MCMC chains and related lists of samples from a function or distribution. Pippi can merge, parse and plot sample ensembles ('chains'), either in terms of the likelihood/fitness function directly, or as implied posterior probability densities. Plots are created natively in pdflatex, using ctioga2. With the addition of a user-defined function, pippi can also post-process ('pare') chains. Pippi is similar to getdist, but tastes more like duck than chicken.
