Test control

Live data displays

The Display Views panel is a workspace for creating charts to display live channel data while the test is running.

To create the first chart, select the desired channels from the Channels list. To add a new chart, drag a channel into an empty area of the Display Views panel. A dialog opens showing a list of available chart types. See Selecting a display type for more information.

Add channels to an existing chart by dragging a channel onto the chart window or by clicking the chart window to make it the active window and selecting channels from the Channels list.

Deselect all channels in the Channels panel to empty a chart. Save the Test Setup with the empty chart in the Display Views. An empty chart may be imported into another Test Setup. For more information see Managing display views about Import... below.

To add a digital meter containing all test channels (up to the current maximum of 100), click the Show All Channels in DVM button at the top of the Channels list.

TIP
Change chart options including the default chart type and size in User preferences. Change the default chart and decimal places for each channel in the Input channels spreadsheet.

NOTE
Live display views can be configured before a test run is started and also while a test is running. When a test is running the user should pay attention to the CPU load indicator on the status bar to understand how much additional processing load is being consumed to drive the live displays. This can be significant and there is the possibility that the CPU will overload and the system will reset on error. The system is designed to preferentially disable the live displays when the CPU load is too high, but this functionality may not always work.

NOTE
The actual rendering of the live display charts is done on the client device (for example, on a PC or tablet). For most modern client devices with high processor or graphics accelerator speeds, the client device will usually not be a factor.

However, for reasons beyond the scope of this help topic, the web browser used can be a significant factor. As of the present software version, the user is strongly advised to use one of the recommended browsers. For more information, see Recommended browsers.

A related issue is antivirus software running on the client device. Using HTTPS will minimize the likelihood of antivirus software negatively impacting display capabilities. For users who are not connected to the Internet, disabling antivirus software should be considered.
