Vis.js – 基於瀏覽器的動態 JavaScript 可視化庫

1、總結

一句話總結：Vis.js 是一個動態的，基於瀏覽器的可視化庫。該庫被設計爲易於使用，能處理大量的動態數據。該庫由如下幾部分組成：一是數據集和數據視圖，基於靈活的鍵/值數據集，能夠添加，更新和刪除項目，訂閱數據集變化；二是時間軸，用於顯示不一樣類型的時間軸數據，在時間軸上項目能夠交互移動，縮放和操縱；三是圖形，使用節點和邊顯示一個交互式圖形或網絡。

 

一、vis庫由哪些部分組成？

數據視圖
時間軸
圖形

一是數據集和數據視圖，基於靈活的鍵/值數據集，能夠添加，更新和刪除項目，訂閱數據集變化；javascript

二是時間軸，用於顯示不一樣類型的時間軸數據，在時間軸上項目能夠交互移動，縮放和操縱；css

三是圖形，使用節點和邊顯示一個交互式圖形或網絡。html

簡述

vis.js 基於瀏覽器的動態可視化庫。該庫被設計爲易於使用，處理大量的動態數據，並支持對數據的操做和交互。該庫由組件DataSet，Timeline，Network，Graph2d和Graph3d組成算法

添加節點以及添加連線的方法
  1. 簡單的添加兩個節點，以及一條連線（除此以外 nodes 和 edges 還支持 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"}]);

這裏寫圖片描述
2. 比較複雜的在線編輯，在 option 中啓用 manipulation 配置：addNode、editNode、deleteNode、addEdge、editEdge 和 deleteEdge。數組

var options = {
            autoResize: true, // Default：true 若是爲true，則網絡將自動檢測其容器什麼時候調整大小，並相應地從新繪製本身。若是爲false，則能夠在使用函數redraw（）和setSize（）調整容器的容器大小後強制從新繪製網絡。
            clickToUse: false, // Default：false 將網絡配置clickToUse爲時，只有在激活時纔會對鼠標和觸摸事件作出反應。激活時，網絡周圍會顯示藍色陰影邊框。經過點擊該網絡將網絡設置爲活動狀態，而後經過點擊網絡外部或按ESC鍵將其更改成非活動狀態。
            width: "100%", // 畫布的寬度。能夠百分比或像素
            height: "100%",
            locale: "cn", // 選擇區域設置。默認狀況下，該語言是英語。
            locales: locales, // 語言環境 默認狀況下 'en'， 'de'， 'es'， 'it'， 'nl' 'pt-br'， 'ru' 的支持。
            configure: {
                enabled: false, // 打開或關閉配置界面。
                filter:  function(option, path){
                    return path.indexOf('physics') !== -1
                }, // 若是布爾值爲true，則給出全部選項，false將不顯示任何值。 若是提供了字符串，則容許如下任意組合：節點，邊，佈局，交互，操縱，物理，選擇，渲染器。隨意想出一個有趣的分開的字符。最後，當提供一個字符串數組時，任何前面提到的字段都被接​​受。當提供一個函數時，你會收到兩個參數。選項對象中的選項和選項的路徑。若是它返回true，則選項將顯示在配置程序中。
// container: undefined,
                showButton: true // 在配置器底部顯示生成選項按鈕。
            },

                    roundness: 0.7 // 0 .. 1.0
                },

                    nodeSpacing:260,// 自由軸上節點之間的最小距離,這僅適用於初始佈局。若是啓用物理，則節點距離將存在有效的節點距離。
                    treeSpacing:260,//不一樣樹木之間的距離（獨立網絡）
                    blockShifting: false, // 每一個節點都會檢查空白，並儘量地將它的分支與它一塊兒移動，並在任何級別上考慮nodeSpacing
                    edgeMinimization: false, // 每一個節點將嘗試沿其自由軸移動以減小其邊緣的總長度
                    parentCentralization: false, // 若是爲true，則佈局算法完成後，父節點將再次居中。
