I was wondering if a boxplot can be overlay be by another boxplot(s)?
I have three groups and two time points in my data and would like to get a graphical presentation on the change in measurement on each group. The measurement is on y-axis, time on x-axis with the three groups superimpose on each other. Ideally, the graph will have six bars; three on time-point 1 and three on time-point 2 with a median connection between bars for each group.
I am using PROC SGPLOT and VBOX statement to generate the boxplot but can't find the right options/ method to get the desire graph. My alternative approach was to using PROC SGPANEL with PANELBY (group) and VBOX statements, but that doesn't help to stack/ overlay the groups. Although the PROC BOXPLOT procedure has more options to customized the graph, but I was not sure (1) if I can overlay bars on a boxplot and (2) if that support ODS GRAPH function.
My best guess is to customized the graph in PROC TEMPLATE procedure, but I am not familiar on that and would like to get some help on that.
If someone could also let me know the code to remove the whisker and outliers on the boxplot, I would really appreciate it.
