The GRAPH/TRACE Option

The GRAPH/TRACE option is used to move along each graph displaying the coordinates as it is traced. The trace cursor appears as a small square with a flashing diagonal line at each corner. This cursor can be moved along the graph by using the left or right arrow keys. The cursor can also be moved to any point by entering its x-coordinate. If the left or right arrow keys are held down, the display will pan left or right to follow the trace cursor.

While tracing, you can press ENTER to adjust the graph screen so that the trace cursor is at the center of the display. This will take you out of trace mode. You can also exit trace mode by pressing CLEAR or EXIT

If more than one function is selected, the up or down arrows can be used to move the trace cursor to the next or previous selected function (the number of the function is shown in the upper right corner of the display).
