如引用 TradingView 庫，需引入庫中 3 個文件（所需庫爲 github 私有庫，需申請）javascript

<script type="text/javascript" src="/static/charting_library-master/charting_library/charting_library.min.js"></script>
<script type="text/javascript" src="/static/charting_library-master/datafeeds/udf/dist/polyfills.js"></script>
<script type="text/javascript" src="/static/charting_library-master/datafeeds/udf/dist/bundle.js"></script>

初始化圖表：html

 TradingView.onready(function () { var chart = window.tvWidget = new TradingView.widget({ symbol: 'd', height: '900', width: '1700', interval: 'D', toolbar_bg: '#c5c5c8', timezone: 'Asia/Shanghai', time_frames: [ {text: "1y", resolution: "1W"}, {text: "6m", resolution: "3D"}, {text: "3m", resolution: "1D"}, {text: "1m", resolution: "1D"}, {text: "1w", resolution: "30"}, {text: "3d", resolution: "30"}, {text: "1d", resolution: "30"}, {text: "6h", resolution: "15"}, {text: "1h", resolution: "1"}, { text: "100y", resolution: "W", description: "All", title: "All" }, ], container_id: 'tv_chart_container', library_path: '/static/charting_library-master/charting_library/', locale: 'zh', //datafeed: new Datafeeds.UDFCompatibleDatafeed("https://demo_feed.tradingview.com"), datafeed: chart_data, //須要顯示的數據內容 disabled_features:[ //'volume_force_overlay',// 成交量與k線分離 ], overrides:{ 'volumePaneSize': 'small', //成交量高度設置，可選值 large, medium, small, tiny } });

我也不知道這是加載圖表仍是什麼，反正就出現圖表了java

function createChartData(){ Datafeeds.Container = function () { //this._configuration=configurationData this._configuration = { supports_search: false, supports_group_request:false, exchanges:[{value: 'DV', name: 'NYSE', desc: 'DeVry Education Group Inc.'}], supported_resolutions: ['1', '15','D','M'], supports_marks: false, supports_time: false, supports_timescale_marks: false, symbols_types: [{name: 'Ny', value: 'dv'}], } } Datafeeds.Container.prototype.onReady = function (callback) { let that = this; getChartData(); if(this._configuration){ setTimeout(function(){ callback(that._configuration); }, 0); } } Datafeeds.Container.prototype.getBars = function(symbolInfo, resolution, dataFrom, dataTo, onHistoryCallback) { onHistoryCallback(dataBar); } Datafeeds.Container.prototype.resolveSymbol = function(symbolName, onSymbolResolvedCallback, onResolveErrorCallback) { onSymbolResolvedCallback({ "name": 'D', "timezone": "Asia/Shanghai", "pricescale": 500, "minmov": 1, "ticker": 'D', "description": "DIdontKnow", "session": "24x7", "type": "bitcoin", "has_intraday": true, "intraday_multipliers": ['1', '30', 'D'], "has_weekly_and_monthly": false, "has_no_volume": false, "regular_session": "24x7" }); } return new Datafeeds.Container; }

數據內容爲本身設置的隨機生成的一些數據，僅供測試使用git

 function getChartData() { var time = 1528404420000; var maxHigh = 8888; var minLow = 8000; for (var i =0; i<10000; i++){ var high = maxHigh - Math.floor(Math.random()*300); var low = minLow + Math.floor(Math.random()*300); var close = high - Math.floor(Math.random()*500); var open = low + Math.floor(Math.random()*500); var volume = parseInt(Math.random()*100); this.dataBar.push({ time:time, close:close, open:open, high:high, low:low, volume:volume }) time += 2000000; } //console.log(dataBar); }
