Is there a name for this kind of diagram? I think of it as the Elite HUD style, but the use of a foreshortened polar grid plus Z-lines to illustrate cylindrical coordinates seems to be popular in astronomical illustrations. I just wonder if it has a better name than "You know, like the scanner in Elite!" — Preceding unsigned comment added by 82.69.29.161 (talk) 18:20, 31 March 2012 (UTC)[reply]
