数据可视化之cytoscape.js

因为数据要展示双向关系,最终选用了cytoscape.js。数据可视化之cytoscape.js_第1张图片

效果如图,echarts只能显示单项数据关系。

据我理解,这个插件分两种,一种是基于jquery的,另一种是原声的。

基于jquery是加在jquery对象上的。因为基于jquery的无法在线上显示关系。最终选择了原生

    elements: data.elements//

});

var layout = cy.layout({
    name: 'concentric',这是控制图形形状的
    fit:true,
    padding: 30, // the padding on fit
    startAngle:4/ 2 * Math.PI, // where nodes start in radians
    sweep: undefined, // how many radians should be between the first and last node (defaults to full circle)
    clockwise: true, // whether the layout should go clockwise (true) or counterclockwise/anticlockwise (false)
    equidistant: false, // whether levels have an equal radial distance betwen them, may cause bounding box overflow
    minNodeSpacing: 100 // min spacing between outside of nodes (used for radius adjustment)
});

layout.run();

这就是简单的初始化及一些配置。
