How a compare series' raw values are mapped before plotting:
'percentage' — percent change vs. the first visible value:
(v / base - 1) * 100. The base is 0%, so all series start at the same
height on the left edge and diverge by relative performance.
'indexed' — the first visible value is pinned to 100:
v / base * 100. Same shape as 'percentage' shifted up by 100.
'price' — no normalization; the raw value is plotted. Useful only when
the compare symbol shares the main series' price magnitude.
'percentage' and 'indexed' share one internal, self-scaling Y axis across
every compare series (see ComparePrimitive) so the lines are directly
comparable regardless of the main price axis. 'price' projects through the
main right price scale (viewport.priceToY).
