本教程比较长,分为2篇发,第一篇为完成图表初始化,第二篇为完成数据接入

第二篇:传送门

  1. 先附上tradingview的文档:查看文档
  2. 图表本身的文件请向官方发邮件申请(贼麻烦,感觉一部分公司审核通过不了)官方git仓库
  3. 推荐一个大神的作品,一开始我也是这样使用的不过后来因为一些原因使用了api的接入方式:https://github.com/webdatavisualdev/vue-tradingview

接下来正式上教程:

1:有些教程是先在index.html中引入chart/charting_library.min.js文件,不过我对文件进行了一些处理(利用export将tradingview导出,不能在这里放出来了),所以只需要在使用的组件中引入即可(直接在index.html中引入charting_library.min.js也是可以达到效果的)

2:创建图表的容器,导入相关文件在生命周期函数mounted中对图表进行初始化(更多设置请查看官方api)

<div id="chart_container"></div>
//数据处理都在这里
import { DataFeeds } from "../../static/chart/datafeed.js";

import { TradingView } from "../../static/chart/charting_library.min.js";
data(){
   return{
      code:'BTC',
      study: [],
      table: null,
      widget: null
   }
},
methods:{
   init() {
      const FALL = "#e34c4c";
      const RAISE = "#00b38f";

      this.widget = new TradingView.widget({
        width: this.$refs.chart.clientWidth,//图的宽
        height: this.$refs.chart.clientHeight,//图的高
        //autosize:true//自动图表大小,经过使用发现没效果。。
        symbol: this.code,//商品名
        container_id: "chart_container",//显示位置
        //参数是数据地址和获取数据频率
        datafeed: new DataFeeds.UDFCompatibleDatafeed(base.market, 2000),
        timezone: "Asia/Hong_Kong",//时区
        interval: "1",//图的周期
        library_path: "../../static/chart/",//本地的图表文件
        locale: "zh",//语言

        ],
        studies_overrides: {
          //柱状颜色修改
          "volume.volume.color.0": FALL,
          "volume.volume.color.1": RAISE,
          "volume.volume.transparency": 30
        },
        overrides: {
          //覆盖操作
          // "paneProperties.background": "#20334d",背景色
          "paneProperties.vertGridProperties.color": "#f8f8f8",
          "paneProperties.horzGridProperties.color": "#f8f8f8",
          "paneProperties.legendProperties.showSeriesTitle": false,
          "paneProperties.legendProperties.showLegend": false,

          "mainSeriesProperties.candleStyle.wickUpColor": RAISE,
          "mainSeriesProperties.candleStyle.wickDownColor": FALL,

          "symbolWatermarkProperties.color": "rgba(0, 0, 0, 0)"
        }
      });
      let widget = this.widget;
      widget.onChartReady(() => {
        if (this.widget === null) return;
        this.table = this.widget.chart();
        this.table.createStudy(//显示成交量
          "Volume",
          false,
          false,
          [],
          entityId => {
            this.study[0] = entityId;
          },
          {
            "volume ma.color": "rgba(132,170,213,0.7)"
          }
        );
        this.table.setChartType(3);//3为分时图,1为K线图
      });
    }
}

3:完成了上面这些,便完成了图表的初始化,接下来便是最关键的数据的接入
