I am using proc sgplot to plot a boxplot. but how can I add a star sign above the significance variables?
this is my boxplot figure, I want to add a sign in the last two box (red and green) to mark them as significant, since there P-value less than 0.05.
Here is my code:
proc sgplot data=boxplot_1;
vbox lab_value / category = treatment group = group
refline 0 / axis = y lineattrs = (color = black thickness = 2);
xaxis display=(nolabel) type = discrete labelattrs = (size = 15pt Weight = Bold) valueattrs = (size = 20pt);
yaxis grid labelattrs = (size = 20pt Weight = Bold) valueattrs = (size = 15pt);
keylegend / location = inside position = topleft across = 1;
Any way to help me.

Here is an example that you can use and edit. Basically you need to create the observations in your dataset at the correct y value and use the markerchar option:
data cars; set sashelp.cars; run; data cars2; invoicey = 100000; make = "Acura"; char = "*"; output; invoicey = 100000; make = "Audi"; char = "*"; output; invoicey = 100000; make = "BMW"; char = "*"; output; run; data cars3; set cars cars2; run; proc sgplot data = cars3; where make in ("Acura" "Audi" "BMW"); scatter x = make y = invoicey / markerchar = char markercharattrs=(size = 15 color = red); vbox invoice / category = make; run;
