AxesOn AxesOff LabelOff LabelOn ExprOn ExprOff Sets axes on or off. Sets axes label off or on. Sets expression display on or off. Format settings define a graph's appearance on the display. Format settings apply to all graphing modes. Seq graphing mode has an additional mode setting (Chapter 6). Changing a Format Setting To change a format setting, follow these steps. 1. Press †, ~, }, and | as necessary to move the cursor to the setting you want to select. 2. Press Í to select the highlighted setting. RectGC, PolarGC RectGC (rectangular graphing coordinates) displays the cursor location as rectangular coordinates X and Y. PolarGC (polar graphing coordinates) displays the cursor location as polar coordinates R and q. The RectGC/PolarGC setting determines which variables are updated when you plot the graph, move the free-moving cursor, or trace. • RectGC updates X and Y; if CoordOn format is selected, X and Y are displayed. • PolarGC updates X, Y, R, and q; if CoordOn format is selected, R and q are displayed. CoordOn, CoordOff CoordOn (coordinates on) displays the cursor coordinates at the bottom of the graph. If ExprOff format is selected, the function number is displayed in the top-right corner. CoordOff (coordinates off) does not display the function number or coordinates. GridOff, GridOn Grid points cover the viewing window in rows that correspond to the tick marks on each axis. GridOff does not display grid points. GridOn displays grid points. AxesOn, AxesOff AxesOn displays the axes. Chapter 3: Function Graphing 75
