How to add legend in ggplot for each facet?
I have the following data.frame. I want to draw a ggplot having three legend tables, the common legend for size, and two separate legends for var = "A" and var = "B" taking the values from 'value' column, these two legends should be placed next to each related graph. So far I have tried this which is creating a single legend for 'var' column.
df <- data.frame(var = c("A","A","B","B"),
value = c("u","v","x","y"),
point = 1:4,
size = 1:4)
ggplot() +geom_point(data = df,
aes(x = point,y = NA,
color = value,size = size)) +
facet_grid(rows = vars(var))
Thanks.
Edit:
I have attached the expected output as suggested by @Tung

What about something like this:
library(gridExtra)
library(ggplot2)
# split data for each "facet"
df <- split(df,f = df$var)
# plot for the first "facet"
p1 <- ggplot(df$A,aes(x = point,y = NA,colour = value, size = size)) +
geom_point() +
facet_wrap(~var, ncol=1) +
# here you set the axis
scale_x_continuous(limits = c(0.5, 4.5))
# do it for each "facet"
p2 <- p1 %+% df$B
# here the plot
grid.arrange(p1,p2)
