Measurement Markers

Use the Measurement Marker on toolbar or context menu to add a measurement marker line to a view. A measurement marker line identifies a location for comparison purposes, and also allows for the measurement of distance between multiple locations on a graph.

After using the icon, moving the mouse over the view shows the potential marker lines that can be added. Clicking within the view adds a marker at the indicated position. The mouse stays in the "add marker" state until you add a marker or select the Measurement Marker icon again.

Values of markers are displayed on the legend area of the graph. Right-click inside the graph view to enable or disable the Legend option from the graph context menu.

If the legend is not enabled by default, as soon as a marker is added, legend becomes visible.
