Can anyone tell me if it is possible to have two labels on the x axis of a
bart chart. For example if I have 6 bars in 2 groups of three can I label the
groups 1 and 2 and the individual bars i, ii, iii, iv, v, and vi. I know one
can do this by having a legend, but I want to have all the labels below the X
axis in line with the relevent bar.

MAny thanks
