axes in 2D


How can I do to change the default behavior of the axes in 2D.
I mean, I want a fixed size for axes, like in the left example
of the Test42 class.

In order to do that, I've had:
boolean b = true;
but it doesn't make any difference with b = false.

Could you tell me what I have missed.

Another thing: Is there a possibilty to display axes on both side,
I mean East + West and North + South?

Thanks a lot.
