Binding Data

The Gauge has 5 data fields available for binding :

• Actual Value : value displayed as a filling of the Gauge
• Start Value : dynamic minimum value
• End Value : dynamic maximum value
• Target Value : target displayed as an arrow on the Gauge
• Series : how we split series of different gauges in the same container
  

Actual Value

This represents the primary quantity we want to display on the Gauge, and will bind to the needle position and filling of the Gauge.

This field must be aggregated : you must choose an aggregation function (SUM, AVG, …)
This field is required.

Start Value

This represents the Minimum we want to display on the Gauge, for example the “MinEU” field from Wonderware Historian.
When this field is bound, it overrides manual configuration of the Custom Range Minimum.

If the Actual Value goes below this Start Value, the Gauge will appear empty.

This field must be aggregated : you must choose an aggregation function (SUM, AVG, …).
This field is optional.

End Value

This represents the Maximum we want to display on the Gauge, for example the “MaxEU” field from Wonderware Historian.
When this field is bound, it overrides manual configuration of the Custom Range Maximum.

If the Actual Value goes above this End Value, the Gauge will appear empty.

This field must be aggregated : you must choose an aggregation function (SUM, AVG, …).
This field is optional.

Target Value

This represents the Target we want to display on the Gauge, and will bind to the position of a small arrow on the Gauge.
When this field is bound, an additional information is displayed as text : the distance from Actual Value to Target Value in units and in percentage.

The Target Value field must be aggregated : you must choose an aggregation function (SUM, AVG, …).
This field is optional.

Series

This represents the series field to generate a different contained Gauge for each different value in this Series field.
Each Gauge will take a portion of size of the widget depending on the container shape. In order to access the other values, the user may need to scroll.
Please see the corresponding chapter to configure the Gauge as Widget container.

*Note :
This only works if your series are values into a single data field.

Example : If you have a field called “Equipment”, you may want to plot a completely separate Gauge for each value of Equipment :
