This week’s symbol is an easy-to-use target to actual comparison. Data like this can be especially important for providing context to operators who may not know that targets are veering off-course without a clear example of target ranges at hand.
The labels can be changed to anything, such as “Desired”, “Preferred”, “Ideal”, etc. In addition to the numeric displays there is a bar graph below showing the target and actual values. Both the numeric display for Actual Value and the bar graph are red until they are less than the target value. There is a “Range” tag that allows some tolerance. For example if the target is 50, and the range is 5 the bar graph and numeric display will change green at 45. The default value for “Range” is 0.
Data Display Target vs. Actual
Range (if applicable): -999 to 9999
- This symbol contains only native IWS objects.
Properties: See below
|Label||The text that will show centered at the top of the display|
|LabelActual||This is the text label that will show on the right side of the display|
|LabelTarget||This is the text label that will show on the left side of the display|
|DesiredMin||Min value of light blue area in the middle|
|TagActual||This is the tag value that will show on the right side of the display and in the bar graph at the bottom. The rectangle/bar will change color based on Actual, Target, and Range tags.|
|TagRange||This is the “Tolerance” value. Default to 0. A positive value will change the color of the bar/display if the actual value is less than the target by this amount. A negative value will change the color if the actual value is greater than the target by this amount. Can use a tag or a constant.|
|TagTarget||This is the tag value that will show on the left side of the display and the white indicator on the bar graph|
Ideas for improvement:
- Add different colors
- Add a Yellow, or Caution range
- Create in different sizes
- Add a display for the difference or delta between target and actual
