Setting Graph Styles for Functions MATH Graph Style Icons in the Y= Editor This table describes the graph styles available for function graphing. Use the styles to visually differentiate functions to be graphed together. For example, you can set Y1 as a solid line, Y2 as a dotted line, and Y3 as a thick line. Icon Style ç Line è Thick é Above ê Below ë Path ì Animate í Dot Description A solid line connects plotted points; this is the default in Connected mode A thick solid line connects plotted points Shading covers the area above the graph Shading covers the area below the graph A circular cursor traces the leading edge of the graph and draws a path A circular cursor traces the leading edge of the graph without drawing a path A small dot represents each plotted point; this is the default in Dot mode Note: Some graph styles are not available in all graphing modes. Chapters 4, 5, and 6 list the styles for Par, Pol, and Seq modes. Setting the Graph Style To set the graph style for a function, follow these steps. 1. Press o to display the Y= editor. 2.
