Variable plotting spaces I: continuous variables

By default every facet of a plot has the same axes. If the data ranges vary wildly between facets, it can be clearer if each facet has its own scale. This is achieved with the scales argument to facet_grid().

  • "fixed" (default): axes are shared between facets.
  • free: each facet has its own axes.
  • free_x: each facet has its own x-axis, but the y-axis is shared.
  • free_y: each facet has its own y-axis, but the x-axis is shared.

When faceting by columns, "free_y" has no effect, but we can adjust the x-axis. In contrast, when faceting by rows, "free_x" has no effect, but we can adjust the y-axis.

  • 1
    • Update the plot to facet columns by cyl.
  • 2
    • Update the faceting to free the x-axis scales.
  • 3
    • Facet rows by cyl (rather than columns).
    • Free the y-axis scales (instead of x).
