Handle (shorter supported) minor-curve not-in-view 

Solve this by always scaling the y-range for the major/target curve
*before* the final overlay scaling loop; this implicitly always solve
the case where the major series is the only one in view.

Tidy up debug print formatting and add some loop-end demarcation comment
lines.
