Vis.js – 基于浏览器的动态 JavaScript 可视化库

1、总结

一句话总结：Vis.js 是一个动态的，基于浏览器的可视化库。该库被设计为易于使用，能处理大量的动态数据。该库由如下几部分组成：一是数据集和数据视图，基于灵活的键/值数据集，能够添加，更新和删除项目，订阅数据集变化；二是时间轴，用于显示不一样类型的时间轴数据，在时间轴上项目能够交互移动，缩放和操纵；三是图形，使用节点和边显示一个交互式图形或网络。

 

一、vis库由哪些部分组成？

数据视图
时间轴
图形

一是数据集和数据视图，基于灵活的键/值数据集，能够添加，更新和删除项目，订阅数据集变化；javascript

二是时间轴，用于显示不一样类型的时间轴数据，在时间轴上项目能够交互移动，缩放和操纵；css

三是图形，使用节点和边显示一个交互式图形或网络。html

3、vis.js 小记

 
简述

vis.js 基于浏览器的动态可视化库。该库被设计为易于使用，处理大量的动态数据，并支持对数据的操做和交互。该库由组件DataSet，Timeline，Network，Graph2d和Graph3d组成算法

添加节点以及添加连线的方法
  1. 简单的添加两个节点，以及一条连线（除此以外 nodes 和 edges 还支持 update 和 remove 操做）
network.body.data.nodes.add([{id: "addNode01",label: "add01",level: 5},{id: "addNode02",label: "add02",level: 5}]);
network.body.data.edges.add([{id: "addEdge01",from: "addNode01",to: "addNode02"}]);

这里写图片描述
2. 比较复杂的在线编辑，在 option 中启用 manipulation 配置：addNode、editNode、deleteNode、addEdge、editEdge 和 deleteEdge。数组

var options = {
            autoResize: true, // Default：true 若是为true，则网络将自动检测其容器什么时候调整大小，并相应地从新绘制本身。若是为false，则能够在使用函数redraw（）和setSize（）调整容器的容器大小后强制从新绘制网络。
            clickToUse: false, // Default：false 将网络配置clickToUse为时，只有在激活时才会对鼠标和触摸事件作出反应。激活时，网络周围会显示蓝色阴影边框。经过点击该网络将网络设置为活动状态，而后经过点击网络外部或按ESC键将其更改成非活动状态。
            width: "100%", // 画布的宽度。能够百分比或像素
            height: "100%",
            locale: "cn", // 选择区域设置。默认状况下，该语言是英语。
            locales: locales, // 语言环境 默认状况下 'en'， 'de'， 'es'， 'it'， 'nl' 'pt-br'， 'ru' 的支持。
            configure: {
                enabled: false, // 打开或关闭配置界面。
                filter:  function(option, path){
                    return path.indexOf('physics') !== -1
                }, // 若是布尔值为true，则给出全部选项，false将不显示任何值。 若是提供了字符串，则容许如下任意组合：节点，边，布局，交互，操纵，物理，选择，渲染器。随意想出一个有趣的分开的字符。最后，当提供一个字符串数组时，任何前面提到的字段都被接​​受。当提供一个函数时，你会收到两个参数。选项对象中的选项和选项的路径。若是它返回true，则选项将显示在配置程序中。
// container: undefined,
                showButton: true // 在配置器底部显示生成选项按钮。
            },
            nodes : {
                font:{
                    color: "#eee",

                    roundness: 0.7 // 0 .. 1.0
                },
                color: "#737373" // 线条颜色
            },

                    levelSeparation: 260,//不一样级别之间的距离。
                    nodeSpacing:260,// 自由轴上节点之间的最小距离,这仅适用于初始布局。若是启用物理，则节点距离将存在有效的节点距离。
                    treeSpacing:260,//不一样树木之间的距离（独立网络）
                    blockShifting: false, // 每一个节点都会检查空白，并尽量地将它的分支与它一块儿移动，并在任何级别上考虑nodeSpacing
                    edgeMinimization: false, // 每一个节点将尝试沿其自由轴移动以减小其边缘的总长度
                    parentCentralization: false, // 若是为true，则布局算法完成后，父节点将再次居中。
                    direction:'UD', // UD, DU, LR, RL
                    sortMethod: 'directed' // directed hubsize
                }
            },
