How to display value in a stacked bar chart by using geom_text?

Question

I would like to display the percentage figures in the stacked bar. However, one group has a really low percentage. Two values are overlapping each other. I change to \'posti

Answer 1

one solution is to change the stack bar to a dodge one

x4.can.bar <- ggplot(data=x4.can.m, aes(x=factor(YearQuarter), y=value,fill=canopy)) + 
                    geom_bar(stat="identity",position = "dodge",ymax=100) +
             geom_text(aes(label =paste(round(value*100,0),"%",sep=""),ymax=0), 
                       position=position_dodge(width=0.9), vjust=-0.25)
x4.can.bar
