The TRangeCircularGauge control implements a circular gauge to specify colors according to the range of the primary variable. It defines the title, adds center text, links to a specific data value, and sets range start and end values. It customizes the gauge arc's start and sweep angles and sets the pointer type. The control configures the legend display, shape, and position. Users can define range segments, their start and end values, color, width, and rounding radius, and assign legend labels, allowing real-time data visualization and differentiation of gauge segments.

Configuration
The TRangeCircularGauge control implements a circular gauge with settings to specify colors according the range of the main variable.
Range Circular Gauge Settings | |
|---|---|
Field | Description |
Header | Defines the title of the gauge. For example example, the header can be set to "SPEED," indicating the type of data displayed. |
Center Text | Allows the user to add text in the center of the gauge. This field is currently empty. |
Linked Value | Links a specific data value or source to the gauge. In this example, it is set to "Tag.Speed," ensuring the gauge reflects real-time speed data. |
Range Start | Defines the starting value of the gauge range. Set to 0, this establishes the minimum value the gauge can represent. |
Range End | Specifies the ending value of the gauge range. Set to 100, this establishes the maximum value the gauge can represent. |
Start Angle | Determines the starting angle of the gauge arc. Set to 135 degrees, this customization allows the gauge to start at a specified point on the circle. |
Sweep Angle | Defines the extent of the gauge arc in degrees. Set to 270 degrees, this determines how much of the circle the gauge will cover. |
Pointer Type | Sets the type of pointer used in the gauge. Options include "Range Pointer" and potentially others, with the current selection being "Range Pointer." |
Legend | Enables the legend display. |
Legend Shape | Defines the legend shape from: Triangle, Circle, Diamond, Rectangle. |
Position | Defines the legend position from: Auto, Bottom, Left, Right, Top.
|
Range | Indicates the specific range segment. Users can enable or disable each range by marking the checkbox next to the range entry. |
Range Start and End | Defines the starting and ending values for each range segment. This setting determines the minimum and maximum values for each color segment of the gauge. |
Color | Specifies the color for each range segment. This setting allows users to visually differentiate between various segments of the gauge. |
Start and End Width | Defines the width of the start and end points of each range segment. This setting determines the thickness of the segment boundaries on the gauge. |
Rounded | Determines if the ends of each range segment are rounded. Users can specify the rounding radius. |
Legend | Allows users to assign a legend label to each range segment. This setting helps in identifying the purpose of each color segment on the gauge. |
Runtime Execution
In Runtime, the control has embedded controls to allow the Operator to modify the view. Typically the configuration settings of <> is attached to a Tag exposed in the Display User Interface, allowing the operator to select <.>.
