Analysis Workspace: Date Format within Graphs

I would like to be able to choose the date format for graphs.

Reponse received from Adobe Client Care (Incident: 161222-000123):

It has been designed to display the month only once for the first date of the month that appears in the graph. Thereafter, the month will again display when there is a change. For example, if a report spans the date range 20 Oct - 02 Jan, then the month Oct will appear below 20, Nov below 01, Dec below 01 and again Jan below 01. So, until you see the next month, it can be assumed that the previous displayed month continues. Hope that clarifies!
