Outstanding Features

The yFiles.NET library enables you to create feature-rich Windows Forms-based diagramming applications. It features all essential functionality from the yFiles product family.

Powerful Graph Controls

yFiles.NET provides powerful Windows Forms controls that enable intuitive interaction with diagrams.
  • Easily edit and handle diagrams with simple mouse gestures.
  • Benefit from out-of-the-box support for zooming and panning, undo/redo, clipboard functionality, image export, and printing.
  • Enjoy smooth change animations and "magnetic" guide lines for manual element alignment.
  • All interaction capabilities are easily customizable to fit your specific needs.

Graph Analysis and Automatic Layout

yFiles.NET provides a wide variety of graph analysis algorithms, that let you tackle the most challenging analysis tasks easily.
  • The suite of automatic 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 layout demands.

Source Code Demo Applications

yFiles.NET 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.NET:
  • 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, save, and print graphs, and export graphs to images

Graph Viewer

The Graph Viewer demo application demonstrates user interaction possibilities such as zooming, panning, overview, and toggling additional node information.

Organization Chart

The Organization Chart demo application shows how to create an interactive organization chart with data loaded from XML.

Collapsible Tree

The Collapsible Tree demo application loads a tree with many nodes, whose branches can be expanded and collapsed. 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.NET. Group nodes can be collapsed or expanded. Whenever group nodes are 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.
