Display Formats

You can select from multiple format options for displaying data on the Data View tab. To change the format of a display, right-click the display and select one of the View As options from the shortcut menu. The number of options available depends on the data type of the signal.

Note Note  The View As option only appears in the shortcut menu of a display if the display contains data that you can view in a different display format.

Graphs

Graphs are the most common type of display in LabVIEW SignalExpress. Time-domain, frequency-domain, and xy signals always appear on graphs on the Data View tab. One graph can display multiple signals only if the signals are of the same type. For example, if you try to add a frequency-domain signal to a graph that displays a time-domain signal, a new graph appears to plot the frequency-domain signal because the signals are different signal types.

Additional Display Format Options

In addition to graphs, you can choose from the following formats to display data on the Data View tab:

Display Format Supported Data Types Description
Numeric Display Scalar (integers only) Displays the numeric value of an integer scalar.
Vertical LED Boolean Displays an LED that indicates the value of a Boolean signal.
Chart Display Boolean, Scalar Displays a plot of a Boolean or scalar signal and a legend that includes the name and current value of the signal. The chart display updates periodically and maintains a history of the signal data previously stored. Right-click the plot and select History Length from the shortcut menu to specify the number of samples to store in a chart history. The number of samples is the number of data points LabVIEW SignalExpress uses to plot the signal. You also can specify how a chart display updates the plotted data by right-clicking the plot and selecting one of the following Update Mode options from the shortcut menu:
  • Strip Chart—Shows data continuously scrolling from left to right.
  • Scope Chart—Shows one item of data scrolling partway across the plot from left to right. When the data reaches the right border, LabVIEW SignalExpress erases the plot and begins plotting again from the left border.
  • Sweep Chart—Similar to a scope chart except that when LabVIEW SignalExpress begins plotting again from the left border the plot shows both the old data and the new data separated by a vertical line.
Slider Scalar Displays a vertical slide filled to the value of the signal.
Table Display Boolean, Scalar Displays a table that includes the name and current value of the signal.
Tank Scalar Displays a tank filled to the value of the signal.
Thermometer Scalar Displays a thermometer filled to the value of the signal.
Gauge Scalar Displays a gauge with a needle that indicates the value of the signal.
Large Display Boolean, Scalar (double-precision only), String Displays the value and units of the signal in large text.
Meter Scalar Displays a meter with a needle that indicates the value of the signal.
