I am trying to plot a stacked bar graph that looks like this:

I know that adding position="identity" or position="dodge" produces different types of bar plots but am not sure how to produce the above chart with both types. Any suggestions?

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')
