Graphs
|
|
======
|
|
|
|
The *Graphs* tab provides a viewer facility for graph data stored in ArangoDB.
|
|
It allows browsing ArangoDB graphs stored in the *_graphs* system collection or
|
|
a graph consisting of an arbitrary vertex and [edge collection](../../Appendix/Glossary.md#edge-collection).
|
|
|
|
|
|
|
|
Please note that the graph viewer requires canvas (optional: webgl) support
|
|
in your browser. Especially Internet Explorer browsers older than version 9
|
|
are likely to not support this.

Graph Viewer
|
|
------------
|
|
|
|
|
|
|
|
Top Toolbar Functions:
|
|
|
|
- Load full graph (Also nodes without connections will be drawn. Useful during graph modeling setup)
|
|
- Take a graph screenshot
|
|
- Start full screen mode
|
|
- Open graph options menu
|
|
|
|
Default Context Menu (mouse-click background):
|
|
|
|
- Add a new node
|
|
- Close visible context menu(s)
|
|
|
|
Node Context Menu (mouse-click node):
|
|
|
|
- Delete node
|
|
- Edit node
|
|
- Expand node (Show all bound edges)
|
|
- Draw edge (Connect with another node)
|
|
- Set as startnode (The Graph will rerender starting the selected node and given options (graph options menu))
|
|
|
|
Edge Context Menu (mouse-click edge):
|
|
|
|
- Edit edge
|
|
- Delete edge
|
|
|
|
Edge Highlighting (right-mouse-click node):
|
|
|
|
- Highlight all edges connected to the node (right-click at the background will remove highlighting)
|
|
|
|
|
|
|
|
### Graph Viewer Options
|
|
|
|
Graph Options Menu:
|
|
|
|
- Startnode (string - valid node id or space seperated list of id's): Heart of your graph. Rendering and traversing will start from here. Empty value means: a random starting point will be used.
|
|
- Layout: Different graph layouting algoritms. No overlap (optimal: big graph), force layout (optimal: medium graph), fruchtermann (optimal: little to medium graph).
|
|
- Renderer: Canvas mode allows editing. WebGL currently offers only display mode (a lot faster with much nodes/edges).
|
|
- Search depth (number): Search depth which is starting from your start node.
|
|
- Limit (number): Limit nodes count. If empty or zero, no limit is set.
|
|
|
|
Nodes Options Menu:
|
|
|
|
- Label (string): Nodes will be labeled by this attribute. If node attribute is not found, no label will be displayed.
|
|
- Add Collection Name: This appends the collection name to the label, if it exists.
|
|
- Color By Collections: Should nodes be colorized by their collection? If enabled, node color and node color attribute will be ignored.
|
|
- Color: Default node color.
|
|
- Color Attribute (string): If an attribute is given, nodes will then be colorized by the attribute. This setting ignores default node color if set.
|
|
- Size By Connections: Should nodes be sized by their edges count? If enabled, node sizing attribute will be ignored.
|
|
- Sizing Attribute (number): Default node size. Numeric value > 0.
|
|
|
|
Edges Options Menu:
|
|
|
|
- Label (string): Edges will be labeled by this attribute. If edge attribute is not found, no label will be displayed.
|
|
- Add Collection Name: This appends the collection name to the label, if it exists.
|
|
- Color By Collections: Should edges be colorized by their collection? If enabled, edge color and edge color attribute will be ignored.
|
|
- Color: Default edge color.
|
|
- Color Attribute (string): If an attribute is given, edges will then be colorized by the attribute. This setting ignores default node color if set.
|
|
- Type: The renderer offers multiple types of rendering. They only differ in their display style, except for the type 'curved'. The curved type
|
|
allows to display more than one edges between two nodes.
