Hello everyone I was trying to add some text below the x axis in ggplot2
and I was able to do so using geom_text
and with help of coord_cartesian
but I couldn't make it reproducible as this need to run in a loop. I thought that adding the values I want with the row names (First, Second) in a table would fix it, does anybody have experience in that. below is the workaround I did. Thank you very much in advance.
## Data
Grade <- 1 : 20
Case <- rep(paste('case' , 1:5,sep = ''),4)
Number <- paste('n', 1:20 , sep = '')
Class <- c(rep('Class1',5) , rep('Class2',5) , rep('Class3',5) , rep('Class4',5))
se <- 0.2
df <- data.frame(Grade,Case ,Number, Class , se)
## plot
ggplot(df, aes(x= factor(Case , levels = c('case1','case2' , 'case3' , 'case4','case5')) , y=Grade ,
fill= Grade)) +
geom_bar(position="dodge", stat="identity",
colour="black",
size=.4) +
geom_errorbar(aes(ymin=Grade +se, ymax=Grade +se),
size=.3,
width=.2,
position=position_dodge(.9))+
geom_linerange(aes(ymin = Grade , ymax = Grade +se),position=position_dodge(.9))+
geom_text(aes(label=Number , y = Grade + se + 1),data=df, position=position_dodge(0.9), size= 4) +
ggtitle('Place a table below x axis')+
facet_grid(~Class) +
xlab('') +
ylab('Case Num') +
theme_gray()+
theme(plot.margin = unit(c(1,1,1,6), "lines"),
axis.text.x = element_text(size = 15)) +
scale_x_discrete(labels = paste(1:5 , '\n' , 10:15, sep = '')) +
geom_text(data = df[df$Class == 'Class1',],x = -1 , y = -3,
label= 'First\nSecond' , size = 4)+
coord_cartesian(clip = "off" , xlim = c(1, 5) )
