Specify how to aggregate the state history.
You can specify one of the following methods.
|count||Count the number of the state history that has a non-null value in the target field.|
|sum||Calculate the sum of the values in the target field.|
|max||Determine the maximum value of the target field.|
|min||Determine the minimum value of the target field.|
|mean||Calculate the average of the values in the target field.|
You can select the method "max", "min", and "mean" only when the target field has the data type "integer" or "decimal".
Currently, the thing console only allows you to browse the aggregated results. You cannot browse the state history as is. If you want to browse non-aggregated state history, use the data browser.
