One label on the y axis and the second one leave it at the top. Using facet_wrap with 2 variables

I want to add a y-axis on each facet. facet_wrap(scales="free_y") doesn't do what I want because switch=y moves both variables and I want to move only one.

  • Is it possible to do something about it?
  • Do you know if there is another way to get the axis on each facet the same way scales="free_y" does?.

Thank you for the time.

the plot that I want

#code for figure 
 ggplot(df,aes(factor(Year),Value,colour=Model,group=Model))+
geom_line(size=0.6)+
  scale_colour_manual(values = c("Black","blue","darkgreen","red"))+

scale_x_discrete(labels=c(1981,2005,2026,2050,2075,2100),breaks=factor(c(1981,2005,2026,2050,2075,2100)),expand = c(0.04,0.04))+
  facet_grid(Variable~Location,scales = "free_y",switch = "y", # flip the facet labels along the y axis from the right side to the left
             labeller = as_labeller(c(CDD = "CDD (Days)",CWD="CWD (Days)",R20="R20 (Days)",R50= "R50 (Days)",R95P="R95P (mm)",R99P="R99p (mm)",
                                      RX5DAY="RX5DAY (mm)",SDII="SDII (mm/day)",Bimodal="Bimodal",Unimodal="Unimodal")))+
  labs(x="Year",y=element_blank(),colour=element_blank())+
  guides(colour = guide_legend(override.aes = list(size = 2)))+
  theme_bw(base_size = 15)+
  theme(strip.background = element_blank(), # remove the background
        strip.placement = "outside",legend.position = "bottom",
        legend.text = element_text(size = 15),
        axis.text = element_text(colour="black"))#,
        panel.spacing.x = unit(-0.90, "lines"),
        panel.spacing.y = unit(-0.80, "lines"))```

Maybe this is what you are looking for. One way to get a y-axis on each facet is to make use of patchwork, i.e. make separate plots for each column of the grid and glue the plots together. One drawback: Both x-axis get labelled:

library(ggplot2)
library(dplyr)
library(patchwork)

make_plot <- function(d, switch = NULL) {
  ggplot(d, aes(factor(Year), Value, colour = Model, group = Model)) +
    geom_line(size = 0.6) +
    scale_colour_manual(values = c("Black", "blue", "darkgreen", "red")) +
    scale_x_discrete(labels = c(1981, 2005, 2026, 2050, 2075, 2100), breaks = factor(c(1981, 2005, 2026, 2050, 2075, 2100)), expand = c(0.04, 0.04)) +
    facet_grid(Variable ~ Location,
               scales = "free_y", 
               switch = switch, # flip the facet labels along the y axis from the right side to the left
               labeller = as_labeller(c(
                 CDD = "CDD (Days)", CWD = "CWD (Days)", R20 = "R20 (Days)", R50 = "R50 (Days)", R95P = "R95P (mm)", R99P = "R99p (mm)",
                 RX5DAY = "RX5DAY (mm)", SDII = "SDII (mm/day)", Bimodal = "Bimodal", Unimodal = "Unimodal"
               ))
    ) +
    guides(colour = guide_legend(override.aes = list(size = 2))) +
    labs(x = "Year", y = NULL, colour = NULL) +
    theme_bw(base_size = 15) +
    theme(
      strip.background = element_blank(), # remove the background
      strip.placement = "outside", legend.position = "bottom",
      legend.text = element_text(size = 15),
      axis.text = element_text(colour = "black")
    )  
}

p1 <- make_plot(filter(df, Location == "Bimodal"), switch = "y")
p2 <- make_plot(filter(df, Location == "Unimodal"), switch = "y")


p1 + p2 + plot_layout(guides = "collect") &
  theme(legend.position='bottom')
