AttributeError: 'MCMCResults' object has no attribute 'plot_z'

Working through the tutorials in your documentation and using some test data from a stock webscrape I get the following error:

AttributeError: 'MCMCResults' object has no attribute 'plot_z'

Here's the model fitting code:

Apple7dCleanedDFModel = pf.ARIMA(data=Apple7dCleanedDF, ar=2, ma=0, family=pf.Normal())
Apple7dCleanedDFModelFit = Apple7dCleanedDFModel.fit('M-H')
Apple7dCleanedDFModelFit.plot_z()

I'm guessing this is an easy fix...

Thanks!
