Unique Key
The Unique Key dialog box is used to specify a unique key for the real time chart. It appears when you select the Incremental Fetch button in the Bind Data screen of chart in the Web Report Wizard, or select the button in the Insert Chart dialog box, Chart Wizard, or Convert to Chart dialog box.

Sorts the view elements in alphabetical order. Elements that are not in any category will be sorted first, then the categories, and the elements in each category will also be sorted alphabetically.

Unique Key
Lists the fields you have added as the unique key, which is used to guarantee there are no two records with the same unique key value in the real time chart.
When a real time chart is specified with a unique key, each time when the chart automatically updates itself, the data that has the same unique key value as the previous loaded data records will be filtered and only data with different unique key value will be added to the chart. For instance, if you add the fields Country and Product ID as the unique key of a real time chart, when a record with the product ID 1 in USA has already been loaded into the chart, no more records of this product ID in USA will be added to the real time chart because they have the same unique key value. The most common usage is with a time field so when a time is part of the unique key the data in the chart will be updated each time new records are added to the database with more recent times.
