Set a max label value on the Y-axis

[jurahero]

Hi,

first of all thanks for the great library.

Would it be possibly to set a max label value on the YAxis?

What I am trying to achieve is the following:

The highest possible value that can be displayed in my chart is 17. Therefore I would only like to show YAxis-label and lines until 15. At the moment, however the chart automatically draws a label / line at 20.
