Hello. I'm struggling with plotting these data in
ggplot. I want a secondary x-axis for a multiple barplots that denotes the
Subgroup. What I currently have is one-level x-axis wherein the data for the
Subgroup is superimposed rather than a side-by-side barplot. Here's the data and the plot that I have generated so far:
# Create some sample data # Create some sample data df = tribble(~Col,~Name,~Subgroup,~Group,~Mean,~Error, 1,'X',1,'Group 1',3.5,0.1, 2,'Y',1,'Group 1',4.9,0.2, 3,'Z',1,'Group 1',1.2,0.2, 4,'A',1,'Group 2',1.1,0.2, 5,'B',1,'Group 3',0.7,0.2, 6,'C',1,'Group 4',0.8,0.3, 7,'D',1,'Group 5',3.7,0.1, 8,'X',2,'Group 1',2.8,0.1, 9,'Y',2,'Group 1',1.5,0.1, 10,'Z',2,'Group 1',1.3,0.2, 11,'A',2,'Group 2',1.2,0.2, 12,'B',2,'Group 3',1.5,0.2, 13,'C',2,'Group 4',0.9,0.5, 14,'D',2,'Group 5',1.1,0.1 ) y1 = ggplot(df, aes(x=Name, y=Mean, fill=Group)) + theme_classic() + labs(y = 'Y') + geom_bar(position=position_dodge(), stat="identity", colour='black') + geom_errorbar(aes(ymin= Mean - Error, ymax= Mean + Error), width=.2, position=position_dodge(.9))
I want to remove the legend since the primary x-axis (i.e.
Name) for the identification. What I want here is a secondary axis for the
Subgroup. It should look something like this except for the
Let me know if you have an idea how to do this. Thanks!
