Setting the Display Style for a Function For each defined function, you can set a style that specifies how that function will be graphed. This is useful when graphing multiple functions. For example, set one as a solid line, another as a dotted line, etc. Displaying or Changing a Function's Style Tip: To set Line as the style for all functions, press ‡ and select 4:Reset Styles. From the Y= Editor: 1. Move the cursor to highlight the applicable function. 2. Select the Style menu: TI.89: Press 2 ˆ. TI.92 Plus: Press ˆ. ¦ Although the Line item is initially highlighted, the function's current style is indicated by a Ÿ mark. ¦ To exit the menu without making a change, press N. 3. To make a change, select the applicable style. Style Line Dot Square Thick Animate Path Above Below Description Connects plotted points with a line. This is the default. Displays a dot at each plotted point. Displays a solid box at each plotted point. Connects plotted points with a thick line. A round cursor moves along the leading edge of the graph but does not leave a path. A round cursor moves along the leading edge of the graph and does leave a path. Shades the area above the graph. Shades the area below the graph. If You Use Above or Below Shading The TI-89 / TI-92 Plus has four shading patterns, used on a rotating basis. If you set one function as shaded, it uses the first pattern. The next shaded function uses the second pattern, etc. The fifth shaded function reuses the first pattern. When shaded areas intersect, their patterns overlap. From the Home You can also set a function's style from the Home screen or a Screen or a Program program. Refer to the Style command in Appendix A. 112 Chapter 6: Basic Function Graphing
