Simple Question - Range of Means on Graph Builder

[#1]

Hello,

When I click Caption Box, and choose range for summery statistic, it gives me the range of the entire data set (which is about 25, from the data points 91 to 116). I was wondering if it's possible for the Caption Box to give me the range of the means (red lines), which around be about 95 to 110.

Thanks.

I think you have to add new column to your table and then use that for caption box
