The Unique Key dialog helps you to specify a unique key for the real time chart. This dialog 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, Chart Wizard, or Convert to Chart dialog.
Lists all the elements in the business view used by the real time chart.
Sorts the view elements in the specified order from the drop-down list. Once a user changes the order, it will be applied to all the resource trees where business view elements are listed for this user.
- Predefined Order
Sorts the view elements in the order defined in the Business View Editor on Logi JReport Designer.
- Resource Types
Sorts the view elements by resource type, namely category objects come first, then group objects, then aggregation objects, and at last detail objects.
- Alphabetical Order
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.
Launches the search bar to search for view elements. For the usage of the search bar, see Search.
Adds the selected fields to the Unique Key box.
Removes the selected from the Unique Key box if they are not required.
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.
