Thanks for bringing this up. We'll look into this.

Hi Fred,

the size of the scrollbar is correct, but a small problem occurs heights that are not even: the right button is rendered one pixel too right.

So set scrollbar Height = 16
and
.Border.Style = BorderType.None

By default Border.Style is Outer and renders the border width count of pixels outside the graph size. That can be easily seen if hiding the Y axis.
