Selecting Graph Styles
Depending on which graphing mode is set, the TI -86 offers up to seven distinct graph styles.
You can assign these styles to specific functions to visually differentiate each from the others.
For example, you can show y1 as a connected line ( » y1= in the equation editor) and y2 as a
dotted line ( Â y2= ), and shade the area above y3 ( ¾ y3= ).
Also, you can manipulate the styles to illustrate actual phenomena graphically, such as a ball
flying through the air (using Á) or the circular movement of a chair on a Ferris wheel (using À).
Icon Style Characteristics of the Plotted Function
»
Line A solid line connects each plotted point; this is the default in Connected mode
¼
Thick A thick solid line connects each plotted point
¾
Above Shades the area above the function
¿ Below Shades the area below the function
À Path A circle cursor traces the leading edge of the function and draws a path as it plots
Á Animate A circle cursor traces the leading edge of the function as it plots; does not draw a path
Â
Dot A small dot represents each plotted point; this is the default in Dot mode
To set the graph style from a program, select GrStl( from the CATALOG (A to Z Reference).
The TI - 86 graphs all selected
functions on the same graph
screen.
¾ (shade above) and
¿ (shade below) are available
only in Func graphing mode.
 (dot) is available in all
graphing modes except
DifEq
graphing mode.
