Markers
The coordinates of any point on a graph can be displayed
using the graph Marker function.
To turn the Marker function on, click anywhere on the
graph. Click the graph again to freeze the Marker. To turn off the
Marker, click the graph a third time.
When the Marker turns on cross-hairs will be displayed at a
point on the graph near the mouse cursor.
Move the mouse to roughly position the cross-hairs.
To move the cross-hairs one position to the left, press F3. To move the
cross-hairs one position to the right press F4.
The x- and y-values of the graph at the cross-hairs will be
displayed numerically at the bottom of the graph. More:
