What does plotter mean?
A plotter is most commonly a person who secretly schemes, especially someone who plots against another person or organization. The word often suggests calculated, deceptive, or unlawful behaviour, although it can be used more broadly for any persistent planner. In technical and scientific settings, a plotter is instead a device or software system that converts numerical information into graphs, charts, or maps. The two meanings share the idea of laying out or representing a course of action, but the everyday sense is strongly associated with conspiracy and intrigue. The word is useful in both literary and technical contexts because it links a human activity—careful plotting—with the older meaning of a plot as a small area of land and with the later development of plotting information on a surface.

Where does plotter come from?
The word comes from the English noun “plot,” which originally referred to a small piece of land and later developed the sense of a scheme or plan, especially a secret or illegal one. Adding the agent suffix “-er” produced “plotter,” meaning a person who makes plots. In modern technical usage, the same word was extended to a machine that plots data graphically.
