Outstanding Features

yFiles for Java 3.0 allows you to create rock-solid Java diagramming applications that use the full range of possibilities provided by the Java Swing toolkit. It features all essential functionality from the yFiles product family.

Powerful Graph Controls


The powerful Java Swing components of yFiles for Java enable intuitive interaction with diagrams.
  • Easily edit and handle diagrams with simple mouse gestures.
  • Enjoy smooth change animations and "magnetic" guide lines for manual element alignment.
  • Benefit from out-of-the-box support for zooming and panning, undo/redo, clipboard functionality, image export, and printing.
  • Customize interaction capabilities easily to fit your specific needs.
  • Import and export SVG, PDF, PS, EMF, and more.
  • Create applications supporting BPM visualizations and specialized automatic layout for BPMN.

Graph Analysis and Automatic Layout


yFiles for Java provides a wide variety of graph analysis algorithms that let you tackle the most challenging analysis tasks easily.
  • The suite of automatic graph layout algorithms includes Hierarchic, Orthogonal, and Circular layout styles to automatically yield clear and concise diagrams from your data.
  • Routing algorithms optimize connection lines in existing diagrams.
  • Ample configuration possibilities suit even sophisticated diagram layout demands.

Java 8 Support


yFiles for Java 3.0 has full support for Java language level 1.8, including lambda expressions, default methods, streams, and generics.
If your Java application needs support for legacy versions of the Java platform before Java 8, we recommend to use the yFiles for Java 2.x line for your application, the yFiles for Java 3.0 predecessor built for the Java 1.4 runtime and later versions like 5.0, 6, and 7.

Showcase Application

Source Code Demo Applications

yFiles for Java 3.0 ships with the full source code of the following demo applications.
To experience the automatic layout algorithms in action, please have a look at the Layout Styles online demo in the yFiles Demo Browser application.

Graph Editor

The Graph Editor demo application is a fully-featured showcase of the visualization and automatic layout capabilities of yFiles for Java 3.0:
  • Add, delete, move, and label nodes and edges to create a graph
  • Interact using zoom and pan, undo/redo, copy/paste, and more
  • Apply graph layout algorithms
  • Load and save graphs from GraphML, export graphs to images

Layout Styles

The Layout Styles demo showcases the various automatic diagram layout algorithms of yFiles, including hierarchic, organic, orthogonal, tree, circular and balloon styles. Additionally, it presents the powerful and highly customizable graph editing capabilities of the graph view component.

Graph Viewer

The Graph Viewer demo application demonstrates user interaction possibilities such as zooming and panning. Graphs from various domains are loaded and enriched with extra information for descriptions and tooltips during the loading process.

Organization Chart

The Organization Chart demo application displays an interactive organization chart with data loaded from XML.

Business Process Models

This sample application allows you to create and edit Business Process Diagrams (BPMN) , and to arrange them with the specialized BPMN layout algorithm.

Collapsible Tree

The Collapsible Tree demo application displays a tree-like structure that can be expanded and collapsed interactively. The nodes are rendered with custom icons that indicate their current state. After an expand or collapse operation, the graph is redrawn using a configurable layout algorithm.

Grouped Graph

The Grouped Graph demo application presents the grouping support of yFiles for Java 3.0. Group nodes can be collapsed or expanded. Additionally, when a group node is expanded or collapsed, a new incremental layout is calculated and the graph is redrawn.

Custom Styles

The Custom Styles tutorial shows how to easily change the look and feel of nodes, edges, and labels to create attractive visual representations of graph structures.
