Both x axis and y axis is by default locked at zero of each other. Only
after you set `axis.axisLine.onZero` to `false` can you unlock and move it as
you wish.

@pissang @plainheart I think setting `axisLine.onZero` as true by default
would be sometimes very confusing, because it will make `axis.position` and
`axis.offset` completely dead before user find out there's a `onZero` locking
these options. I would suggest we at least clarify in documentation that user
should turn off `onZero` before they use `position` and `offset`.
