Solid Gauge Properties

Field Name Description
Title Enter a title to help identify the solid gauge at runtime.
Value See Set Up Data Binding for Widgets
Min Enter the minimum value for the solid gauge scale.
Max Enter the maximum value for the solid gauge scale.
Use Raw Format Select the check box to display numbers in raw format.

For example, a numeric value with 5 or more decimal places is shown as it is, and not rounded off.
Number of decimals This option appears if you do not want to display numbers in raw format.

In that case, enter the decimal places (0-7) to consider after the decimal point to format large numbers. Based on the decimals, the value is rounded off to the nearest whole number.

The decimals will apply to Value, Min, and Max properties.
Engineering Unit Enter the unit of measurement for the values on the gauge.
Width (px) (0 equals Dynamic) Enter a width for the solid gauge. If set to 0, the widget occupies 100% of its container, and fills the area in the application.
Background Color Select a background color to fill the widget.
Font Color Select a font color for the widget text.
Font Size (px) (0 equals Dynamic) Specify a font size in pixels for the solid gauge display text. If set to 0, the font resizes to match with the width of the widget.
Sparkline The sparkline data is created based on the query applied to the widget. We can see a sparkline only if the query returns multiple records from the data source. The sparkline is not displayed for a single record even if it is enabled.

Select the check box to enable the sparkline for the selected Gauge Variant at runtime.
Gauge Variant List of different types of gauges you can use in your application.
Text position Select a position to display text for the solid gauge at runtime.
  • Top Left is the default position.
  • You can choose to position the text at the Center of the gauge.
Range(s) You can specify one or more ranges to display in different colors.
To add a range:
  1. Select +Add Item.
  2. Enter a value for limit. At runtime, the gauge is displayed in the selected color on reaching this value.
  3. Select a color for the range limit.
The ranges are implemented in the specified order. To set the order:
  • Use and to reorder ranges.
To delete a range:
  • Select to delete a range.
Dynamic Range(s) This property allows you to set the ranges based on real-time data retrieved from a query. Instead of manually defining static ranges, this feature lets the gauge adapt its ranges dynamically according to the latest data, making your gauge more responsive to changing conditions.
Dynamic Alert Limits Similar to dynamic ranges, this property enables the gauge to adjust its alert thresholds based on data obtained from a query.
Alert Limit(s) You can add one or more alerts on a gauge, each with unique values.
To add an alert:
  1. Select +Add Item.
  2. Enter a value for limit. At runtime, a line alert is displayed on the gauge on reaching this value.
  3. Select a color to identify the line alert.
The alerts are implemented in the specified order. To set the order:
  • Use and to reorder alerts.
To delete an alert:
  • Select to delete an alert.
Custom Alert Labels Select the check box if you want to display the alert limit labels on the solid gauge.
Result Set Index This property is applicable for REST queries only. It allows to define which index of the result set the widget should use as input data. Default is 0.

For example, consider a Historian REST query that returns data for three tags.

  • If you want the widget to use the first tag data from the query result set, then set the index value as 0.
  • To direct the widget to use the second tag data, enter the index value as 1.
  • Similarly, you can set index values as 2, 3, 4, etc. based on the data to provide as input to the widget.
Reverse Order This property helps to reverse the query result set.

Select the check box to provide the bottom record value as input to the widget.

Clear the check box to provide the top record value as input to the widget.

When you apply this property to REST queries that return more than one record for each input tag, the records of the selected tag (use Result Set Index to select the tag) are reversed.

For example, consider a Historian REST query with two input tags (tag1 and tag2); each with 100 records as result. Set the Result Set Index as 0 and verify the following:

  • If you selected the Reverse Order check box, then the 100th record (last) value of tag1 is displayed on the gauge.
  • If you cleared the Reverse Order check box, then the first record value of tag1 is displayed on the gauge.
Hidden Select this check box if you want to hide the widget. To show the hidden widget in Operations Hub new layout, go to Page Visuals and under Action column, select for the hidden widget. See Page Visuals Tab.
