The Dagre layout for DAGs and trees for Cytoscape.js (demo)
The dagre
layout organises the graph using a DAG (directed acyclic graph) system, written by Chris Pettitt. It is especially suitable for DAGs and trees. For more information, please refer to Dagre's documentation.
Download the library:
npm install cytoscape-dagre
,bower install cytoscape-dagre
, orImport the library as appropriate for your project:
ES import:
import cytoscape from 'cytoscape';
import dagre from 'cytoscape-dagre';
cytoscape.use( dagre );
CommonJS require:
let cytoscape = require('cytoscape');
let dagre = require('cytoscape-dagre');
cytoscape.use( dagre ); // register extension
AMD:
require(['cytoscape', 'cytoscape-dagre'], function( cytoscape, dagre ){
dagre( cytoscape ); // register extension
});
Plain HTML/JS has the extension registered for you automatically, because no require()
is needed.
Call the layout, e.g. cy.layout({ name: 'dagre', ... }).run()
, with options:
var defaults = {
// dagre algo options, uses default value on undefined
nodeSep: undefined, // the separation between adjacent nodes in the same rank
edgeSep: undefined, // the separation between adjacent edges in the same rank
rankSep: undefined, // the separation between each rank in the layout
rankDir: undefined, // 'TB' for top to bottom flow, 'LR' for left to right,
align: undefined, // alignment for rank nodes. Can be 'UL', 'UR', 'DL', or 'DR', where U = up, D = down, L = left, and R = right
acyclicer: undefined, // If set to 'greedy', uses a greedy heuristic for finding a feedback arc set for a graph.
// A feedback arc set is a set of edges that can be removed to make a graph acyclic.
ranker: undefined, // Type of algorithm to assign a rank to each node in the input graph. Possible values: 'network-simplex', 'tight-tree' or 'longest-path'
minLen: function( edge ){ return 1; }, // number of ranks to keep between the source and target of the edge
edgeWeight: function( edge ){ return 1; }, // higher weight edges are generally made shorter and straighter than lower weight edges
// general layout options
fit: true, // whether to fit to viewport
padding: 30, // fit padding
spacingFactor: undefined, // Applies a multiplicative factor (>0) to expand or compress the overall area that the nodes take up
nodeDimensionsIncludeLabels: false, // whether labels should be included in determining the space used by a node
animate: false, // whether to transition the node positions
animateFilter: function( node, i ){ return true; }, // whether to animate specific nodes when animation is on; non-animated nodes immediately go to their final positions
animationDuration: 500, // duration of animation in ms if enabled
animationEasing: undefined, // easing of animation if enabled
boundingBox: undefined, // constrain layout bounds; { x1, y1, x2, y2 } or { x1, y1, w, h }
transform: function( node, pos ){ return pos; }, // a function that applies a transform to the final node position
ready: function(){}, // on layoutready
sort: undefined, // a sorting function to order the nodes and edges; e.g. function(a, b){ return a.data('weight') - b.data('weight') }
// because cytoscape dagre creates a directed graph, and directed graphs use the node order as a tie breaker when
// defining the topology of a graph, this sort function can help ensure the correct order of the nodes/edges.
// this feature is most useful when adding and removing the same nodes and edges multiple times in a graph.
stop: function(){} // on layoutstop
