The axis.labelWidth is calculated incorrectly, if it isn't set by the user. The default is divide by 6, while it should actually be divided by the number of ticks.

axis.labelWidth=canvasWidth/6

should become:

axis.labelWidth=canvasWidth/axis.ticks.length

Hi! Thanks for the comment. I think it was like that in the beginning, but something made me hardcode it. Or maybe I'm wrong. Have you tested it with a various layouts?

Yeah, it works perfectly for 7, 8, 30 and 31 ticks. I'm guessing that it works for all numbers.

There's another patch that redoes this part of the code, but that's currently stalled. So I'm merging it now. Thanks!
