This article proposes a decorated parallel coordinate plot for longitudinal data featuring a jitter mechanism revealing the diversity observed longitudinal patterns and allowing the tracking of each pattern variable point and line widths reflecting weighted frequencies the rendering of simultaneous events and different options for highlighting typical patterns. The proposed visual has been developed for describing and exploring the temporal of events but it can be equally applied to other types longitudinal categorical data. Alongside the description of the plot we demonstrate the scope of the plot with two real applications.
