Hi all,

In a graph which I am trying to draw with LuaMetafun, I have a variable the 
values of which I want to show on the graph rotated 90 degrees (or whatever 
other value).
Is it possible to do that?

An example is:

        numeric a, u ; u := 10mm ;
        a := 4.5 ;
        label.bot(a, (10,-0.1) scaled u) % I would like to have printed 4.5 
rotated 90 degrees for instance.

Thanks in advance for any help: Otared
