Using this unique feature, complex data sets can be visualized and arranged even more clearly. Grouping of Diagram Elements yEd enables grouping of diagram elements, to virtually any nesting degree. Label Placement Another of yEds excellent features is its ability to automatically assign label positions, enabling you to easily improve your diagrams, with each label clearly readable. Orthogonal Edge Router re-routes connections in existing drawings in orthogonal manner. Tree layout can consider labels for layout calculation and provides additional alignment options.Ī dedicated Swimlane layout algorithm automatically arranges the elements in Swimlane diagrams.Ĭonnections Organic Edge Router re-routes connections in existing drawings in an organic style. Tree Layout can be used to clearly visualize tree-like structures in many different ways. The layout can be restricted so that it fits into a given area (e.g., a rectangle, circle, or ellipse) or a specified aspect ratio.Ĭircular Layout can perfectly portray interconnected ring and star topologies. Organic Layout produces clear representations of complex diagrams like ER diagrams, UML diagrams, and many more. UML-style Orthogonal Layout offers special support for arranging UML class diagrams, for example. Each subsequent simple mouse click (left mouse button) that does not occur on a node then creates a further bend.Hierarchical Layout enables you to perfectly visualize hierarchical or pseudo-hierarchical scenarios. To create an edge with multiple line segments the mouse drag gesture must end at an empty place within the drawing canvas, i.e., the mouse button must be released to create a first bend. However, the mouse drag gesture must start, respectively end on the group node’s label or the border of the group node.Īn additional bend in an edge is created by a mouse drag gesture that starts on the edge.Įdge creation can be aborted by clicking either the right mouse button or the ESC key.Įdges can also consist of multiple line segments, i.e., they can have bends. Group nodes can also be created by dragging a sample group node representation from the Palette tool window to the active editor window with a mouse drag gesture.Īdding/Removing a Node to a Group Node/from a Group NodeĪ node can be added to a group node or can be removed from a group node by holding the SHIFT key while moving the node into the group node or out of it, respectively.Ĭreating an Edge that Starts/Ends at a Group Node Note: Source node and target node can be identical.Ī so-called group node can be created by using the item “Group” of either the drawing canvas’ or the node’s context menu. (The edge can be seen as soon as the mouse cursor “leaves” the source node’s area.) If there are selected graph elements, then no node will be created but theĪn edge is created by a mouse drag gesture that starts on a node (the source node) and ends on a target node. The mouse click must occur at an empty place within the drawing canvas. Mouse button) within the active editor window if option Nodes contained in a group node can be connected to nodes outside the group node as well.Ī node can be created by dragging any of the sample node representationsįrom the Palette tool window into the active editorĪdditionally, it is possible to create a node by a simple mouse click (left So-called group nodes are special nodes that in turn can contain proper graph structures with nodes and edges. Visual elements that represent entities from arbitrary application areas are called nodes, lines that connect two nodes and thus define a relationship between them are called edges.Įdges can consist of multiple line segments that are connected to each other ending point to starting point these connection points are called bends.
