Thread: labeling column bins in a bar graph

Hello,
I have plotted data in a bar graph. It has four bars indicating performance in each condition. I want to also label the bars so that they indicate the sample size for each condition (n=30, n=30, n=29, n=30). I want to be able to place the labels either inside the rectangular bars or on top of them.

Thus far, I've tried to format the data series but I can't add the sample size labels, e.g. n=30, for each bin in the graph.

Any help is welcome..
thanks,
pete
