mxGraph JavaScript

Installation

The examples can be edited with any texteditor. To run the examples point your browser directly to the local files (use links below) or use a webserver to deliver the files. Note that the files should always be delivered via a webserver in production. Local usage of files is only recommended for development and testing. (Please read this for running examples from the local filesystem in Internet Explorer.)

Examples

javascript/examples/editors contains the following examples:

• Graph Editor - Fully functional diagram editor and drawing application.
• mxDraw - Web 2.0-style diagram editor and drawing application.
• mxProcess - Process editor with a fancy stylesheet and user interface.
• mxWorkflow - BPMN workflow editor with various example diagrams.
• mxWorkflow/Layout - BPMN workflow editor with automatic layout.(Experimental)

javascript/examples contains the following examples:

• Images - Using background images and images for for the label- and image-shape.
• Indicators - Using small subshapes (indicators) inside a parent shape, typically an mxLabel.
• Label Position - Using the label position styles to set the position of vertex labels.
• Labels - Wrapping and clipping for HTML labels of vertices, truncating labels to fit the size of a vertex, and manually placing vertex labels and relative children that act as "sublabels".
• Layers - Using multiple layers to contain cells.
• Merge - Using the mergeChildren function to merge two graphs.
• Monitor - Using mxGraph to display the current state of a workflow.
• Offpage Connectors - Creating offpage connectors in a graph and loading a new diagram on a single click.
• Orgchart - Using automatic layouts, fit to page zoom and poster print (across multiple pages).

• Schema - Implementing a database schema editor.
• Scrollbars - Using a scrollable table with different sections in a cell label.
• Secondlabel - Adding another string label to vertices.
• Shape - How to implement and use a custom shape.
• Stylesheet - Using a custom stylesheet and control points in edges, as well as overriding the getLabel and getTooltip function to return dynamic information, and making a supercall in JavaScript.
• Swimlanes - Using swimlanes for pools and lanes and using the stack layout as an automatic layout.
• Thread - Setting overlays in mxGraph from within a timed function.
• Toolbar - Using existing cells as templates for creating new cells.
• Tree - Folding for subtrees in acyclic graphs (trees).
• UIConfig - Using a config file to configure the toolbar and popup menu in mxEditor.
• Userobject - Using XML objects as values for cells.
• Validation - Using multiplicities for automatically validating a graph.
• Windows - Using the mxWindow class for displaying windows.
• Wrapping - Using HTML markup and word-wrapping in vertex and edge labels.
• HelloPort - Using the isPort hook for visually connecting to another cell.
• Pagebreaks - Using the pageBreaksVisible and preferPageSize switches and adding headers and footers to print output.
• FixedPoints - Using fixed connection points for connecting edges to vertices.
• ServerView - Using a server-side image of the graph as the diagram in the client.
• ContextIcons - Adding icons to selected vertices to carry out special operations.
• Guides - Using the guidesEnabled and snapToTerminals switches, creating a grid using a canvas and handling cursor keys.
• FixedIcon - Customizing the icon position in the mxLabel shape.
• Markers - Creating custom marker.
• Dragsource - Using one drag source for multiple graphs and changing the drag icon.
• Orthogonal - Demonstrates the use of port constraints and orthogonal edge styles and handlers.
