Using the toolbar
The following operations are available in the Graph Browser toolbar menu:
File settings
-
Add: Opens a dialog with the following options:
-
Open a saved graph: Select from the existing saved graphs.
-
Add data from a dashboard: Select a dashboard from the list to add it to the graph.
You can also drag a dashboard from the menu on the left and drop it onto the graph.
-
Add entity identifiers: Select a type of entity identifier to add as nodes in the graph.
-
-
Save: Save the current graph.
-
To image: Save the current graph to an image in PNG format.
-
To IBM i2: Save the current graph with all of the lenses applied and download it as a file that is compatible with IBM i2 Analyst’s Notebook. You must configure the i2 export feature in order to use it. For more information, see Exporting a graph to IBM i2 Analyst’s Notebook.
-
Undo: By default, the Graph Browser saves the last five states. With this function you can go back one step at a time, until there are no more steps available. To configure the number of steps, see Advanced Graph Browser settings.
-
Redo: Revert an undo.
If you click Undo and then perform any operation, the redo state will be lost.
Layout settings
-
Standard: In this layout setting, the selected nodes are presented in a linear format, keeping link lengths consistent and preserving the relative position of the nodes.
-
Hierarchy: In this layout setting, nodes are displayed top-down, according to their connections. This setting requires at least one node to be selected. Selected nodes are placed at the top of the hierarchy.
-
Radial: Arranges nodes in concentric circles.
-
Advanced: This menu button offers a range of layout options:
-
Organic: Arranges nodes in a fan-like pattern, with the larger components in the center. This option is useful for big data sets, because it prioritizes system performance.
-
Sequential: Arranges nodes in a tree-like, hierarchical structure, to minimize the number of crossed links.
-
Lens: Arranges nodes in a circle-like grid with connected nodes next to each other.
-
Structural: Places nodes that are structurally similar together in the network.
-
Tweak: Adjusts node positions in a force-directed, arrow-like layout.
-
Fit: Fits all of the nodes onto the canvas.
-
Selection settings
-
Group: Select multiple nodes and click Group to work with them as a collection.
-
Ungroup: If nodes have been grouped together, you can split them apart so they can be worked with individually.
Removal settings
-
Crop: Removes every element that is not selected.
-
Delete: Deletes the currently selected nodes. Delete all clears the graph completely.
Action settings
-
Expand: Expands the currently selected nodes, so that you can view their relations to other entities.
-
Node position settings: You can change the default policy to move all nodes on expansion, and choose to either move only specific nodes or to fix the position of all nodes by default.
-
Expand by relation: Perform an expansion that is determined by the relations that are selected in the Expansion tab in the sidebar.
-
-
Filter: Adds a filter based on the nodes that you select in the graph. This allows you to:
-
Do your investigation on the graph, select the nodes that you are interested in, activate a filter, pin it, and go back to the related dashboard to get more detailed information about those entities.
-
If you have other visualizations in the same dashboard, it will let you have more information on the selected nodes. For example, if the current dashboard is associated with a companies entity table, you can do your investigation in the graph, activate the filter, select some vertices and get the visualizations to show information on the selected vertices.
-
For more information, see Filtering data.
View settings
-
Map: Select this button to switch the Map mode on or off. The Map mode will move the nodes geographically on an interactive map. You must set up a script to configure the geographic properties of the nodes and configure the Graph Browser to include the script type Add geo-locations for map visualization.
-
Heatmap: You can switch the heatmap on or off.
-
-
Time: Select this button to switch the Timebar mode on or off. This setting displays a time bar at the bottom of the screen that enables time-based filtering of nodes. You must set up a script to configure the time property of the nodes and configure the Graph Browser to include the script type Add time fields.
-
Show nodes without time field:
-
Time filter: Select or deselect the node types or dashboards that you want to be displayed in the time bar.
-
-
Options: The following additional options are available:
-
Highlight connected nodes: Makes the connections between nodes more visible.
-
Invert relations: Shows the inverse of the current relation.
