Is it yet possible to have different axis breaks / limits for individual facets in ggplot with free scale?

I saw that this related question was asked in 2010 (titled: How do you set different scale limits for different facets?) and would like to know if it is yet possible to have different breaks for different facets?

The reason being is that I want only integer values in the lower chart (with breaks of 50 for the top chart) of following plot: enter image description here

Code to reproduce the image:

dat <- data.frame(date=seq(0, 729, 1), Var1=round(seq(from=0, length.out=730, by=0.2)),   Var2=round(seq(from=5, length.out=730, by=0.01))  )
dat.m <- melt(dat, id.var="date")
ggplot(dat.m, aes(date,  value)) + 
      scale_x_continuous(name="Time") + 
      expand_limits(y=0) +
      ylab("Variable") + 
      geom_step() + 
      facet_grid(variable~., scales="free_y")+ 
      scale_y_continuous(breaks = seq(0, 150, by = 1))

First, your code doesn't produce the same plot as on my machine. Can you provide the sessionInfo()?

I don't think it is possible. Best approximation of your request I could achieve in a simple way:

ggplot(dat.m, aes(date,  value)) + 
      scale_x_continuous(name="Time") + 
      expand_limits(y=0) +
      ylab("Variable") + 
      geom_step() + 
      facet_grid(variable~., scales="free_y")+ 
      scale_y_continuous(breaks = c(seq(0, 12, by = 2),seq(0, 150, by = 50)))
