Push axis label fix (#6) to crates.io

[whooie]

Hi, I'm running into an issue that looks a lot like the one shown in #5, where the value labels get placed incorrectly next to the axis ticks.

It seems to have been fixed here on Github, though (and indeed things look right if I use the code pulled directly from this repo), but the version up on crates.io appears not to have been updated yet.

Would you mind publishing the updated version?

No problem, will do when I fix issue #7
