Separate y axis for different facets in ggplot

Question

I would like to create a plot using ggplot where different facets should have different y axis limits. By default each facet has the same y axis values. can this be changed

Answer 1

See ?facet_grid. You want to use the argument scales="free_y".

Answer 2

You can change scales to "free_y" instead.

  facet_grid(facets, margins = FALSE, scales = "fixed",
    space = "fixed", shrink = TRUE,
    labeller = "label_value", as.table = TRUE, drop = TRUE)

For further detail and examples, see: http://docs.ggplot2.org/0.9.3.1/facet_grid.html
