When you link to a data selection gadget that uses the same data object, the same data field name is used by default.

If the data selection gadget uses a different data object, the developer must match the published data field from the data selection gadget to a data field in the subscribing gadget.

For example, a list gadget shows product line names from a data set. A chart gadget shows sales results from a data cube in a different data object. The developer matches the different field names when linking the chart gadget to the list. This enables the list gadget to filter product line data in the chart gadget.

Figure 6‑3 shows two different data fields that are matched.
