Direct data feeding

In this process, the dashboard is loaded from its description file. Utility methods allow you to retrieve symbols of the loaded dashboard, and then to set particular values for the properties. When properties have been mapped to some specific parameters in the Dashboard Editor, the model already contains the corresponding properties to be directly set on the symbols. The following is an example of the code to write when you manage a dashboard through direct data feeding.

Managing a dashboard through direct data feeding

IlvDashboardDiagram _dashboard;

IlvDashboardContext context = new IlvDashboardContext();

// create the dashboard

_dashboard = new IlvDashboardDiagram(context);

String path = "data/dashboard.idbd";

// ......

url = new URL("file:./" + path);

// ......

// Load the dashboard

_dashboard.readDashboard(url);

// Retrieve a given symbol

Object symbol = _dashboard.getObject("my_symbol");

// Set a symbol property

_dashboard.setObjectProperty(symbol, "my_value", new Integer(123));

The application <installdir>/jviews-diagrammer/samples/dashboard/bam/index.html is provided as part of the JViews Diagrammer demonstration software to illustrate how to create dashboards that are directly managed by Java™ code.
