Api for changing axes values

Hello, is there any way to change axes `value` parameter with API?
I'd like to set values myself because i don't really like existing formatting options, so something like `d3.scale.linear().domain([0, 1.51]).ticks()` could generate better tick values (with neat roundings).
But if my series changes - i can't change axes values without chart reconstructing.

Could you please tell me if there's better way to format ticks or how can I change axes values after chart was created? Thanks.
