cytoscape-navigator

Description

Bird's eye view pan and zoom control for Cytoscape.js

Dependencies

• Cytoscape.js ^2.6.0 || ^3.0.0

Usage instructions

Download the library:

• via npm: npm install cytoscape-navigator,
• via bower: bower install cytoscape-navigator, or
• via direct download in the repository (probably from a tag).

require() the library as appropriate for your project:

CommonJS:

var cytoscape = require('cytoscape');
var navigator = require('cytoscape-navigator');

navigator( cytoscape ); // register extension

AMD:

require(['cytoscape', 'cytoscape-navigator'], function( cytoscape, navigator ){
  navigator( cytoscape ); // register extension
});

Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

API

var cy = cytoscape({ /* ... */ });

var defaults = {
    container: false // string | false | undefined. Supported strings: an element id selector (like "#someId"), or a className selector (like ".someClassName"). Otherwise an element will be created by the library.
  , viewLiveFramerate: 0 // set false to update graph pan only on drag end; set 0 to do it instantly; set a number (frames per second) to update not more than N times per second
  , thumbnailEventFramerate: 30 // max thumbnail's updates per second triggered by graph updates
  , thumbnailLiveFramerate: false // max thumbnail's updates per second. Set false to disable
  , dblClickDelay: 200 // milliseconds
  , removeCustomContainer: true // destroy the container specified by user on plugin destroy
  , rerenderDelay: 100 // ms to throttle rerender updates to the panzoom for performance
};

var nav = cy.navigator( defaults ); // get navigator instance, nav

You may call nav.destroy() to remove the navigator widget and associated cleanup.
