Numeric Gauges
Gauges provide the ability to display real time data feeds coming from ACQ on your user interface. You can only display distinct data items (data fields) as full RAW messages are usually not a single numeric value. Gauges come in 3 flavors: Linear, Radial and Numeric. They are very useful for illustrating a progress towards a goal, the current status of some value within a range of upper and lower bounds, or a summary of some fluctuating metric.
Numeric Gauges represent data as a changing numeric value, similar to an old LCD clock.
Designing the Widget
Click the Numeric link under the Gauges group in the Manage My Widgets panel then click the +Create New Numeric Gauge button on top of the grid.
Enter the standard information for widget creation including a name, description, any keywords and permission level you wish this template to have and hit OK.
This will bring you to the editor for this widget.
The editor for numeric gauges is mainly comprised of a tab strip with 2 tabs:
Data Field
The Data Field tab is where you define the source of the numeric data you wish to display with this gauge. Unlike the other gauge types, numeric gauges only support a single source.
Gauge Display
The Gauge Display tab is where you define settings related to the display of the numeric value. You can specify a minimum and/or maximum value, set the color, size, etc of the font and set the method of numeric display. This method must be one of the following:
| Fixed Decimal | Locks in the number of digits after the decimal point |
| Precision | Locks in the total number of digits displayed |
| Exponetial | Uses the scientific / exponential notation to display the value and sets the number of digits after the decimal point (useful for LARGE numbers). |
Run Time
Numeric Gauges are, like other widgets, added to a layout via a Widget Group.
Simply find the Numeric Gauge node and expand it to see a list of all Radial gauge templates available to you. Create a new one if needed or load a previously defined one into your group.
The gauge you select should start and a numeric readout will reflect the current value(s) of the underlying sensor data the gauge is associated with.
