Implement y-scale (ex: log)

Hi Daniel, thanks for helping to develop this library. I was wondering if it'll be (or already is) possible to manipulate the resulting charts much like matplotlib charts, for example:

  • changing the y-scale
  • changing major/minor x-ticks
  • setting chart titles and legends

I'd love to be able to do this with the existing charts. Let me know if I can help. Thanks!
