Describe the bug

When drawing rotated axis labels (e.g. dates and times), they should not overlap with the chart -- their origin should not be at the center but at the top

I have the same problem. I tried using .pos(Pos::new(HPos::Left, VPos::Top)) alongside the font transform, but it didn't do anything 😕
