Widget communication
Some widgets automatically communicate when you create a dashboard. This means that if you perform changes for one widget, for example, changing a filter, that change is propagated through all widgets within the dashboard.
To see the widgets and parameters that are set to communicate automatically, click the Dashboard button > Widget Communication.
You can also manually set up widget communication for some parameters. This is used in the Drillback Report dashboards to enable filtering of other reports when you click a chart. See the Widget list topic for each domain to see which entities have parameters that you can manually set up to communicate.
