This information is accessible in myData in a variable, "qnt".

Here is a slight modification of the second example
in help('wireframe'):

   wireframe(z ~ x * y, data = g, groups = gr,
       scales = list(arrows = FALSE,
           x = list(at = c(2, 5, 10)),
           y = list(at = c(6, 10, 14),
                    lab = c('A', 'BBB', 'CCCCC'))
       ))
