FR - Custom Labels

[michalkonturek]

Initial request created by @crewshin:

Excellent little library you have here. Thanks for sharing.

If there's anything I could nitpick about it's the lack of control with the labels. That and for whatever reason I can't figure out how to keep my lines within the views frame if the value is above 200. They get clipped at the top of the view. Some kind of auto scaling would be nice.

Also a horizontal version of the bar chart would be nice.

Cheers
