You can also move the markers directly on the Graph tab. Drag the
marker to the desired area in the display. You will notice that the
corresponding box in the Markers tab changes according to the
marker’s position. If you want to set a precise value for the marker,
simply enter it in the box.

Note: After using the zoom tools in the Graph tab, you can only move the

markers again on the graph after deactivating the zoom. Pressing the
arrow in the zoom tools section will deactivate the zoom function.

Note: Markers A and B cannot cross. Displacing a marker over the second one

will cause both markers to move together.
