Plot that shows CME 'complexity' follows solar activity. Top panel: relative 'complexity' of every CME in the ranking plotted against time. Red points represent STEREO-A images, while blue points represent STEREO-B images. Annual means are over plotted for STEREO-A (red dashed line) and STEREO-B (blue dashed line) CMEs.
