I created a faceted set of three univariate densities — comparing MCMC methods. Shown below

For the moment, I don’t care about the tails. So how can I change the x-axis limits on the plots above to be:
c(-3,1)
c(-2,0)
c(-10, -8)
Is this even possible? I’ve already read this thread from 2009, but it doesn’t seem to work. Was this implemented?
You can always allow limits to be set independently for each facet by specifying
There are also “free” and “free_y” options.
