Konica and Rodenstock

12 and 8 researched events on one shared scale. Konica 1873–present, Rodenstock 1877–2013.

The axis stretches where either maker has research and collapses where neither does, so a year sits opposite the same year on both. Event counts differ because research depth differs, not because one company did less.
