Hi Grzegorz,
Thanks for the reply, but it gives the same result as my example...: the axis is in fact scaled from 3 to 12, but it gives ticks for 2 4 6 8 10 12...
I need only ticks in the center of the squares, ie here 3 6 9 12, I don't want to see other ticks and labels... that make sense?
Thank you a lot
Camille.
