1) In order to have nice plots you must be able to show/print rotated
text, otherwise your ylabel will look ugly (if you are using gl2ps
I just forgot to implement that. I'll look into it.
2) while the plot_example works for me, I cannot fget help for the
actual plotting functions (e.g. plot_axis) nor can I find them with
e.g. "which plot_axis"
That's because there is no such function. In plot_example.m, there's a local function defined at the end of the file called plot_axis, which is probably what you're looking for.
