Gantt 2.2.3 - remove Day when viewing Hour Date Type

Hi all,

I'm able to render a daily schedule visualization pretty easily:

I have two questions:

1. Is there any way to remove the day that is listed in parenthesis across the horizontal axis? I have the Date type set to "Hour".
2. Is there any way to change the font size of the horizontal axis so that I can fit the entire chart on one screen, without a scrollbar?
