Chapter 3: Function Graphing 71

Setting Graph Styles for Functions

MATH Graph Style Icons in the Y= Editor

This table describes the graph styles available for function graphing. Use the styles to visually

differentiate functions to be graphed together. For example, you can set Y1 as a solid line, Y2 as a

dotted line, and Y3 as a thick line.

Note: Some graph styles are not available in all graphing modes. Chapters 4, 5, and 6 list the

styles for Par, Pol, and Seq modes.

Setting the Graph Style

To set the graph style for a function, follow these steps.

1. Press o to display the Y= editor.

2. Press † and } to move the cursor to the function.

3. Press | | to move the cursor left, past the = sign, to the graph style icon in the first column.

The insert cursor is displayed. (Steps 2 and 3 are interchangeable.)

4. Press Í repeatedly to rotate through the graph styles. The seven styles rotate in the same

order in which they are listed in the table above.

5. Press ~, }, or † when you have selected a style.
