Example of visualizing the process status in a pie chart

A pie chart is used to show the ratio of the time a valve was closed or open. The base signal is a digital signal in the ibaHD-Server.

1. Create a virtual signal in the pie chart tile using the "If" function.

   
   

   

   
   

   Based on the status, the strings "Closed" or "Open" should be returned.

2. Under Available Signals, select a signal that has values for this range.

3. Under Group by Signal, select the virtual signal you created earlier.

4. In the options, select the "Count" function in the Aggregation field.

5. If necessary, change the category colors.

The pie chart shows the ratio of "Closed" (red) to "Open" (green).
