When you select é or ê for two or more functions, the
TI-83 rotates through four shading patterns.
• Vertical lines shade the first function with a é or ê
graph style.
• Horizontal lines shade the second.
• Negatively sloping diagonal lines shade the third.
• Positively sloping diagonal lines shade the fourth.
• The rotation returns to vertical lines for the fifth é or ê
function, repeating the order described above.
When shaded areas intersect, the patterns overlap.
Note: When é or ê is selected for a Y= function that graphs a family of
curves, such as Y1={1,2,3}X, the four shading patterns rotate for
each member of the family of curves.
To set the graph style from a program, select H:GraphStyle(
from the PRGM CTL menu. To display this menu, press
while in the program editor. function# is the number
of the Y= function name in the current graphing mode.
graphstyle# is an integer from 1 to 7 that corresponds to
the graph style, as shown below.
1 = ç (line) 2 = è (thick) 3 = é (above)
4 = ê (below) 5 = ë (path) 6 = ì
(animate) 7 = í (dot)
GraphStyle(function#,graphstyle#)
For example, when this program is executed in Func mode,
GraphStyle(1,3) sets Y1 to é (above).
