Chapter 3: Function Graphing 79

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. In this case, all three graphs of

Y1={1,2,3}X will be the same color.

Setting a Graph Style from a Program

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 8 that corresponds to the graph style, as

shown below.

GraphStyle(function#,graphstyle#)

For example, when this program is executed in Func mode, GraphStyle(1,3) sets Y1 to é (above).

Setting the Viewing Window Variables

The Viewing Window

The viewing window is the portion of the coordinate plane defined by Xmin, Xmax, Ymin, and Ymax.

Xscl (X scale) defines the distance between tick marks on the x-axis. Yscl (Y scale) defines the distance

between tick marks on the y-axis. To turn off tick marks, set Xscl=0 and Yscl=0.

1 = ç (thin)

2 = è (thick)

3 = é (above)

4 = ê (below)

= ë (path)

6 = ì (animate)

7 = (dot-thick)

8 = í (dot-thin)
