10.10. Active Tool Area Marker
Area
Marker
When this tool is active, its icon on the Chart Toolbar and in the Tools > Active
Tool menu will look like this: . When this tool is active and the cursor is
positioned above a Chart, the cursor will look like this: . This tool can be
active simultaneously with other tools. An active state does not necessarily indicate
that the tool will be used when you click in a chart. Instead, an active state shows
that an area marker is active in the chart which has focus. The state of this tool is
maintained individually for each chart. Select the tool again to disable it and hide
all area markers in the active chart.
To select an area, left-click over the first point in a chart while moving the pointer
to the second point. Release the button when done. Repeating this action will
remove the first area marker. This means only one area marker can be shown in
each chart.
The area marker is used to select the ranges to be used for math calculations. For
example, DFT calculations for DFT charts, phasors, or statistic grids.
The appearance and behavior of the area marker tool can be modified on the
Markers property page in the chart's property dialog box. You will find the Free
Selection setting on this page.

If Free Selection is enabled, the Area Marker will not analyze for automatic full-
cycle waveform selection in the Waveform Chart.

If there are several X-axes, and you pan or zoom in on one of them, you may see
two separate area markers. However, if you select a new range, all this will
disappear and be replaced by overlapping markers extending between the points
you selected, independent of the axes zoom and pan states. As waveform samples
may exist at different intervals, this may result in fewer cycles being selected for
some axes than for others. This may be hard to discern, but if you look closely, a
thin, black line will indicate the start and end points of each marker.
