From: Visualising disease progression on multiple variables with vector plots and path plots
Vector plots by sex and condition. Vector plots of annual disease progression with sex encoded by different coloured arrows and data plotted separately for controls and individuals that had neurotransplantations. The grey polygons assist in visualising the population of values; the smaller the area of the polygon in the top left quadrant indicates less disease progression. The mean values for both sexes are shown on the axes, where it can be seen that male controls progressed faster on the tapping score, whereas females progressed faster on the UHDRS.
