About the Data Visualizer

The Data Visualizer gives you a visual depiction of the relationships between the selected data type and its properties, and with the other data types in the application. You can use the Data Visualizer to explore and extend the data map for your data type.

Adjust the display using the four buttons at the top right:

  • Legend - Click to display the legend that explains the shapes, lines, and colors the Visualizer uses.
  • Reset - Click to reset the display as it first appeared.
  • Center - If you have navigated around a large display, click to recenter the display in your browser.
  • Open in Window - Click to open the Data Visualizer in its own window.
  • Collapse - Close the Data Visualizer.

Every node in the diagram represents a Pega Platform class, or a data type (which is, in fact a class). Every entry within the node represents a page or a page-list property of that class.

The properties can be of the following types:

  • Page property.
  • Page list property.
  • Property that is dynamically linked to other properties, rather than having the other properties copied into the class. Referencing rather than copying properties can save system memory.

The lines that join properties can be solid or dotted. A dotted line indicates that a dynamic reference is established between the properties the line connects.

A plus icon at the top left of a node, as with the "Supplier" node in the image above, indicates that there are additional incoming relationships for that node. Click the icon to display those relationships. A minus icon indicates all relationships for that node are visible. Click the icon to hide the relationships.

When you hover over a node in the display, the other nodes with which it is connected turn orange to help you visualize the selected node's relationships.

The Data Visualizer displays related case types.

To edit a second node, as well as the one from which you launched the Data Visualizer, double-click on it. The data type or class type opens in its own tab, and you can edit it there. In that tab, you can click theVisualize button to generate a second Data Visualizer display centered on the second node.

To edit the original node, select the top edge of the Data Visualizer and drag it down to reveal the data type you started with.

You can make edits in the Data Designer view and review their impact in the Data Visualizer.
