Faceting with free y-axis
In the previous plot, all six graphs had the same axis limits. This made the changes over time hard to examine for plots with relatively little change.
Instead, you may want to let the plot choose a different y-axis for each facet.

Instructions
Change the faceted plot so that the y-axis is freely chosen for each facet, rather than being the same for all six.
