Hello,
Thanks for the suggestion below. I did one of my figures and it worked perfectly. I tried it on my second figure and got double-labelling on the first bar. I used the same code to create both figures, and the same code to label. I've attached the code for one of the plots (there were 3/figure) if anyone has a chance to figure out why.
Thanks,
Suzanne
