Starting the trace operation causes a crosshair pointer to appear on the graph. You can then 
press a cursor key or tap the graph controller arrows to move the pointer to the location you 
want, and read the coordinates that appear on the display. To start the trace operation and 
display the pointer, make the 3D Graph window active, and then tap , or tap [Analysis] 
and then [Trace]. 

• Each time you press the cursor key or tap a graph controller arrow, the pointer moves the 

distance specified by the [grid] value on the 3D View Window dialog box. 

• Inputting a value while a trace operation is being performed displays a dialog box for   

inputting an 

- and 

-coordinate. Inputting values for each of the coordinates on this dialog 

box causes the pointer to jump to the corresponding location when you tap [OK]. 

To cancel the trace operation, tap 

 on the icon panel. 

•  The initial default setting for the coordinate display is rectangular coordinates (Rectangular). 

Tapping 

 

and [3D Format] displays the 3D Format 

dialog box

, which you can use to select 

polar coordinates (Polar) or to hide coordinate values entirely. 

•  For details about the settings you can configure on the 3D Format 

dialog box

, see “3D Format 

Dialog Box” on page 1-9-8.

You can insert text into a 3D Graph window and delete it as required.
