alter logic for where spikes start and end
- toaxis always goes from the point to the axis, even for free axes - across spans all counteraxes with subplots for this axis, and extends to the free axis if it exists - fixed a bug with positioning after scrolling gd within a container - also short-circuited calculations we don't need
