Density Plot from Scientific Research

Kernel density estimates of an agent’s course direction relative to the local plume centreline (solid blue) and to the current wind direction (dashed orange) in three plume configurations. ±180° means antiparallel movement with respect to the plume centreline, or exactly upwind movement with respect to the wind direction. e, A substantial proportion of time is spent at an angle (≈45° angle for the switch-once configuration, e ; arbitrary angle for the switch-many configuration, f ) to the wind, but actually aligned (antiparallel) with the plume centreline. Bottom row panel titles indicate how many time steps and how many successful episodes were summarized in each plot.
