Managing Markers

As markers C and D appear on the graph, the power difference between

the markers (C-D) related to the horizontal markers will be displayed in the

marker toolbar.

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 marker toolbar 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.
