An explanation of the Donut Gauge Control for Axiom.

Donut Gauge

A donut ring showing the value of the source tag in the center. The ring changes color to show the value location between the scale low and high values.

Name - The name used by the application and script to reference this control. 

X - Number of pixels from the left edge of the containing panel or screen. 

Y - Number of pixels from the top edge of the containing panel or screen. 

Width - Width of the control in pixels. 

Height - Height of the control in pixels. 

SourceTag - Clicking the trend icon launches the tag browser to select a tag for value input. Clicking the trash can will delete the reference to the tag. 

ScaleLow - The lowest value at the top of the donut. 

ScaleHigh - The highest value to complete the donut in a clockwise direction. 

LimitLow - Adds a second ring with the portion of the arc below this value set to the low limit color (blue). 

LimitHigh - Adds a second ring with the portion of the arc above this value set to the high limit color (red). 

Visible - Unchecking this will hide the control. A script would be required to toggle the visibility during runtime. 

OnClick - An event that occurs when the control is clicked. Clicking "<>" Creates a "DonutGauge1_Click()" script stub for this control and opens the script editor to add event scripting. Clicking the trash can will delete only the reference to the script, not the script. 

OnValueChange - An event that occurs when the SourceTag value changes. Clicking "<>" Creates a "DonutGauge1_ValueChange()" script stub for this control and opens the script editor to add event scripting. Clicking the trash can will delete only the reference to the script, not the script.
