• Name - a unique name used to reference the control in script *
• AggregateInterval - the amount of time within each interval over which the data is processed using an 'AggregateKind' (e.g. 15 minutes, 15m, 00:15:00)
• AggregateKind - the aggregate used to process the data over a given 'AggregateInterval'
• AggregateStartTime - retrieves the value at a specific actual or relative time (e.g. now, day + 6h, 6:00 AM)
• SourceTag - opens the 'ADD TRENDS' menu to link the control to a tag
• ValueTransform - transform data using the keyword, "value", as the variable tag within an expression (e.g. 3.14*Pow(value,2)). Calculations are performed using C# NCalc library. For more information on NCalc functions, click here.
• AngleStart - the start position of the scale in degrees, where 0 equals the 12 o'clock position

• Color - sets the color of the needle
• Height - the height of the control in pixels

  • Value - sets the limit to a static number or other 'SourceTag'
  • Comparison - choose between <, >, >=, <=, or =
  • Color - sets the color for the configured limit
• MajorInterval - sets how often a major tick should appear on the scale
• ScaleMax - the maximum value to appear on the scale
• ScaleMin - the minimum value to appear on the scale
• Width - the width of the control in pixels
• X - the horizontal coordinate of the top-left corner in relation to its parent container
• Y - the vertical coordinate of the top-left corner in relation to its parent container
• OnBeginValueChange - used to trigger a script that runs immediately before the tag value changes *
• OnClick - used to trigger a script that runs when the gauge is clicked *
• OnEndValueChange - used to trigger a script that runs immediately after the tag value changes *
