Plotting a stacked bar plot?

Question

I have the following data:

structure(list(Time = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 
1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 
         


        

Answer 1

ggplot(df, aes(x = factor(Time), y = Value, fill = factor(Type))) + 
geom_bar(stat="identity", position = "stack")

 ggplot(df, aes(x = factor(Time), y = Value, fill = factor(Type))) + 
 geom_bar(stat="identity", position = "dodge")

You can do one or the other but not both. When they are dodged, the different values of type are being used. By adding a color outline, you can see that.

 ggplot(df, aes(x = factor(Time), y = Value, fill = factor(Type))) + 
 geom_bar(stat="identity", position = c("dodge"), colour = 'black')
