Note: To enable faster chart refresh times while a scan is in progress, some zoom and auto-scale toolbar controls are disabled if more than four (4) channels are added to the Strip Chart. To re-enable these toolbar controls, either stop the scan or limit the number of displayed channels to four (4) or fewer.

Note: This gadget is available in the Scan Module configuration only. If you have selected the Switch Module configuration on the Instrument Settings tab, this gadget will not be allowed for this module.

Adding Channels to Strip Chart

  1. To add channels (traces) to the Strip Chart, first you need to define the unit labels for the graph's Y Axis. Note that you can define a different label for the left and right side of the graph, but they cannot be the same units. Select "All" from the drop-down list to display the selected channels on the graph with no axis labels.

  2. By default, the lowest-numbered channel in the current scan list is added as a trace to the strip chart. To add more channels, go to the Select Channels/Markers drop-down at the bottom of the window, click on the Channels tab, and then assign the desired channels. You can also select the desired trace color, vertical scale, and vertical offset.

Markers

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 channels in the current scan list to the two markers, go to the Select Channels/Markers drop-down 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 101 is linked to marker 1 and Channel 102 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 .
