Term for connected graphs[edit]

Hello! While creating the graphic below to illustrate camera angles of view, I wondered if anyone would know the term for graphs where the position on one axis can be directly transferred to an adjacent graph, as illustrated by the yellow line. Though I haven't encountered such graphs elsewhere before, surely I can't be the first to have drawn one! Cheers, cmɢʟeeτaʟκ 23:48, 10 April 2015 (UTC)[reply]

Log-log graphs of focal length vs crop factor vs diagonal, horizontal and vertical angles of view for film or sensors of 3:2 and 4:3 aspect ratios. The yellow line shows an example where 18 mm on 3:2 APS-C is equivalent to 27 mm and yields a vertical angle of 48 degrees.
These may be called lattice graphs or trellis plots. See for instance [1] and [2]. --Mark viking (talk) 11:04, 11 April 2015 (UTC)[reply]
