Hi all,

I want to make a Yleft axis have a rolling effect . Example :

3 -|
2 -|
1 -|
0 -|

now as you pan going up it will look,

2 -|
1 -|
0 -|
3 -|

if you pan some more ....

1 -|
0 -|
3 -|
2 -|

it will always keep the interval's width to be 4 in this case.

How can I implement this? any help would be appreciated.
