Yes, I agree - your specified AXIS1 statement as shown should generate the desired label text format. Suggest you share your code (from the SAS log generated output) for forum subscriber feedback. Also, try making changes to your AXIS1 statement to ensure it is being referenced.

When I run the BOXPLOT example in Chapter 18 in SAS 9.2, using the AXIS statement and the code in the documentation, I get the same results as the picture in the documentation.
However, when I run the same example in SAS 9.1.3, I get the label as you describe. Perhaps this is one of the font improvements in SAS/Graph that is different between 9.1.3 and 9.2 -- you might wish to check with Tech Support to determine whether there is a way, in SAS 9.1.3 to get the results to look as they do in 9.2 and in the doc.
Sounds more like this is one of those frustrating situations where SAS R&D decides to change behavior / output from one version to the next -- something, frankly, that I do not consider to be improvement but in my opinion more like inconsistency.
