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.
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.
