Agreed; horizon charts take some explanation. However, once you understand what they're showing, they become quite natural. That makes them suitable for dashboards that are monitored by a regular audience (say, production engineers, stock traders), since the viewer learns the first time and then benefits subsequently from the concise representation. However, I probably wouldn't recommend them for a mass audience in a one-off visualization, where the effort to understand might be beyond the viewer's patience for a single viewing.
