Hi-
I am experiencing difficulty generating plots of MCMC chains with PyPlot.
It was working fine and "just" stopped working. I even reverted to the
latest working version of the code in Dropbox, but to no avail. Here is
the code and the error message:
p = plot(sim, [:trace, :mean, :density, :autocor], legend=true);
PyError (PyObject_Call) <type 'exceptions.ValueError'>
ValueError('x and y must have same first dimension',)

ret = ax.plot(*args, **kwargs)

sims is a 3 dimensional array with the following properties:
Object of type "Chains"
Iterations = 1:2000
Thinning interval = 1
Chains = 1,2,3,4
Samples per chain = 2000
2000x5x4 Array{Float64,3}:
Any advice would be greatly appreciated. I can also attach the full code I was
using if that is helpful. Thanks in advance.
