Splitting parameter connections

You can split a parameter connection so that two instances of a widget communicate separately.

For example, you have two widgets. When you select a region in one widget, a chart in the second widget updates to display the sales for that region. If you want to compare the sales for two different regions, the first step is to add a second instance of each widget to the dashboard. The dashboard then contains four widgets. But if you select a region in either region widget, both charts update to display sales for that region. So, the second step is to split the parameter connection so that the first region widget only updates the first chart widget and the second region widget only updates the second chart widget.

To split the parameter connection:

  1. Click Dashboard > Widget Communication.
    The Widget Communication dialog box is displayed.
  2. Expand the parameter connection in the Parameter Connections pane.
    The four parameters of the connection are listed: two from the region widget and two from the chart widget.
  3. Drag one of the region widgets to the New Parameter Connection field.
    A second parameter connection is created, with the same name as the first.
  4. Drag one of the chart widgets onto the region widget of the second parameter connection.
    The Widget Communication dialog displays two parameter connections, each with two parameters.
In the dashboard, you can now select different regions in the two region widgets. The two charts update independently.
Note: To make it easier to identify the widgets in the Widget Connection dialog, you might rename the widgets on the dashboard.
