Test control
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. 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.
The Display Views panel can contain many different display views, each with its own named tab. Different views allow for a variety of chart types, sizes, locations and channels. Display views can be created or modified at any time.
To manage views, open the views menu by clicking the menu button () or right clicking in the Display Views panel.
To change the size of a chart, double left-click in the header bar of a chart or click and drag a corner or edge of a chart. Vertical and horizontal scroll bars show on the Display View after a chart is made larger than the Display View. Make a Display View wider by clicking the left-pointing arrows in the Task and Channels panel headers.
The size of a video display may be changed while frozen.
When other charts are frozen during a test, their size may not be changed.
If any chart remains frozen when a test ends, its size may be changed, but the plot will no longer show.
