Setting Data Service Parameters
Many data services have input parameters. For example, when you query a stream, you normally pass in the start and end dates for the stream query, and may pass additional filter criteria to the query. Data service input parameters will appear under the data service if available. Expand the Parameters section to see the input parameters. Input parameters will have an inward facing arrow, indicating they accept incoming bindings. You can bind any parameter to any data point in the mashup that is outward bindable and is of a compatible data type.
When a data service is called, the service automatically pulls any bound input parameters from the mashup before execution. Any widgets bound to the service's data will automatically update when the service is complete.
