What kind of statistical plot do you think can demonstrate both the quantity and std (or mean)?
For example, I have a dataset of a large population in different ages. I used clustering method to separate the population into ten groups based on the Euclidian metric of age. Now I want to examine the population quantity (counts) and age std (or mean) in each clustered group. Ideally, the std for each group will be very small, but their mean increases monotonically.

Thank you for the explanation, Image Analyst. The red line in the boxplot I think is median, not counts (the number of samples in the group).

You're right - I hadn't read the help completely. I guess the mean would be at the halfway point in the blue box. I guess you could draw a line for that if you wanted - unfortunately I don't see an option to have the mean line in there explicitly.
