Generating and loading data model graphs

Generating graphs

Without configuring anything, the add-on can render a new data model graph. Simply open a data model, dataset, or table Actions menu and select Display data model under Visualization. If the option has been enabled by an administrator, you can choose which tables are rendered in the graph. See Changing display and configuration options for information on configuring this option. When you run the service from a:

The following image shows an example data model graph:

Displaying external models

If a data model graph contains a table from a different data model, you can enable display of the external model in the current graph. You can do this for any external table and each graph can contain multiple data models.

To display an external model in an existing data model graph:

  1. Right-click an external table. A graph identifies external tables using the /info-icon-shadow.png icon and an alternate color.

    /display-external-model-1.png

  2. Select Display external model.

    As shown below the external model now displays in the graph, and the above process was repeated to display additional models. See Interacting with data model graphs for additional information on using graph features.

Saving and loading graphs

You can expand, collapse, determine display of, and rearrange graph components. Once satisfied with the appearance, use the Save button at the bottom of the graph to store the current layout and settings. As shown below, you can use the Load button to load a saved graph. When more than one saved graph of the current model exists, select the desired graph and click Generate at the bottom-right of the screen.

Note

If the loaded graph's underlying data model contains changes since its last save, the add-on allows you to choose whether to synchronize the graph. See Visualizing changes to models for more information on synchronization.

Visualizing changes to models

If you are loading a graph after a change has been made to the underlying data model, a pop-up dialog displays and allows you to choose whether to update the graph. As shown below, updated graphs highlight new items in green, changed items in blue, and deleted items in red:

Permissions

If you do not have sufficient permission to view any tables in a given dataset, the Display data model service will not display. If there are certain tables or fields you are restricted from viewing, they do not display when you generate a data model graph.
