Daniel, the author of GraphET is currently on holidays. He will be back very soon.

In the meantime, it is easy to add it manually. Consider the example:

-=-=-=-=-=-=-=-=-=-=

chart verticalBarDiagram 
models: (1 to: 20);
regularAxis;
height: 200.

chart rawView add: ((ROLabel red elementOn: 'Chart about my life') translateBy: 200 @ 0).
chart rawView add: ((ROLabel elementOn: 'Happiness') translateBy: -30 @ -40).
chart rawView add: ((ROLabel elementOn: 'Passing days') translateBy: 430 @ 210)
-=-=-=-=-=-=-=-=-=-=

The screenshot illustrates the result.
