Displaying n values above above bars

smit3000 — Mon, 02 Mar 2020 17:28:13 GMT

Hello,

I'm trying to display the n sample size for each category in my graph above the error bars on my graphs. For example, I'm looking at data and comparing findings from different states, which are my categories, and I'd like to display how many respondents, my n, were in each category.

I do not know how to add such a label. You could, though, display the group size in a second plot.

This way would also allow you to use separate labels for the two kinds of information.

One possibility is to add a Caption Box with the N statistic.
1) Plot your data as desired
2) Right Click on the Plot and select Add > Caption Box (you should see the Overall Mean for the entire data set)
3) Right Click again on the Plot, select Caption Box > Summary Statistics > N
4) 3) Right Click again on the Plot, select Caption Box > Per Factor

This will produce annotation at the top of the graph for each bar.

If that does not meet your criteria, you could create a new column with the n for each category, choose this column as Label, and then use it in Graph Builder as Label by Row

Depending on the organization of your table, the formula for n will be slightly different: a good place to start is "Col Number( :Y, :Category)"
