Inward y-ticks

By default, the y-ticks are aligned to the center of the tick lines. If you want to plot the tick labels strictly inside the track, you can use the pygv.tracks.track.Track.inward_yticks property.

array([<Axes: title={'center': 'chr19'}, ylabel='Default'>,
       <Axes: ylabel='Inward'>], dtype=object)
