Changing the Appearance of a Graph

kChanging the Graph Background

You can use the Setup screen to specify the memory contents of any picture memory area (Pict 1 through Pict 20) as the Background item. When you do, the contents of the corresponding memory area is used as the background of the graph screen.

Example 1 With the circle graph X2 + Y2 = 1 as the background, use Dynamic Graph to graph Y = X2 + A as variable A changes value from –1 to 1 in increments of 1.

Recall the background graph.

(X2 + Y2 = 1)

(When the graph for X2 + Y2 = 1 is stored in Pict 1)
