Configure a basic SA_PieChart symbol using ArchestrA attributes

The basic configuration of the SA_PieChart symbol shows a circular chart with five segments or slices that are assigned measured values. The size of each slice graphically represents the percentage of the assigned measured value to the whole.

To configure a basic symbol, you need to assign references to the PieXX custom properties. For the sake of simplicity, this example uses only two variables to show the basic configuration steps.

Prerequisites

To demonstrate how to create a basic symbol using ArchestrA attributes, create a UserDefined object with the following properties:

• Create two analog PVx attributes as Float data types.

• Enable I/O scaling and clamp to the EU range.

To configure a basic SA_PieChart symbol

1. Embed the symbol in another symbol in the Industrial Graphic Editor.

2. Select the symbol.

3. Show the symbol's list of Wizard options by at the right of the Industrial Graphic Editor window.

4. Set NumberPies to Two.

5. Right-click on the symbol and select Custom Properties to show the Custom Properties dialog box.

6. Assign reference values to the PieXX custom properties and click OK.

   1. Select the Pie01 custom property from the list and click the Galaxy Browser button to the right of the Default Value field.

   2. Click the Attribute Browser tab and select an attribute from the list to assign to the custom property.

   3. Assign a reference value to the Pie02 custom property and click OK.

7. If you want, assign optional string values to the symbol's labels.

   4. Right-click on the symbol, select Substitute, and then select Substitute Strings.

   5. Enter string values into the fields of the Substitute Strings dialog box that match the default strings shown for the symbol and click OK.

8. Save the symbol and check it in.

9. Deploy the Galaxy containing the object with attributes that are used as reference values of the custom properties.

10. Double-click an instance of InTouch ViewApp to start WindowMaker.

11. Embed the symbol containing the symbol in an InTouch window.

12. Run the application in WindowViewer to verify that your basic symbol configuration works correctly.
