When a graph is displayed, you can position two vertical markers to display measurement data for each marker position and display the relative measurement data between the markers (∆M2 ‑ M1). To link specific digitizer channels to the two markers, go to the Select Channels/Markers drop-down menu at the bottom of the gadget window, click on the Markers tab, and then select the desired channel for each.
If the markers are not being displayed on the graph, click to display markers.
To position the markers, click 
or 
and drag the marker left or right. The example above shows marker 1 and marker 2 positioned on the graph with the corresponding marker measurement data displayed below the graph. In this example, Channel 301 is linked to marker 1 and Channel 302 is linked to marker 2.
When a marker is moved off the graph (by zooming in on the trace, for example), it appears at the upper left or right corner of the graph.
To hide markers, click
