【k线】vue中通过echarts.js实现k线图的demo,拿来即用的vuek线demo

基于echarts实现的最基本的k线图，包含k线，均线，macd指标，缩放组件。echarts配置项使用echarts官方实例，这里只是为了演示vue实现k线图。文末有源码。

一，依赖安装

1，echarts

npm install echarts --save

2,v-router路由

npm install v-router --save

二，配置项

1，创建kdemo.vue文件

2，路由配置文件中配置对应路由

我的路由配置文件

import Vue from 'vue'
import Router from 'vue-router'
import kdemo from './views/kdemo.vue'

Vue.use(Router)

export default new Router({
  mode: 'history',
  base: process.env.BASE_URL,
  routes: [
    {
      path: '/',
      name: 'kdemo',
      component: kdemo
    },
  ]
})

3，项目正常启动

npm run serve

通过npm run serve命令启动，测试浏览器中输入

“http://127.0.0.1:8081/”

即可正常访问到kdemo.vue文件中内容

4，引入echarts

kdemo.vue中在script标签中引入echarts

var echarts = require("echarts");

5,再template，html标签中创建echarts的挂载实例

<div id="echartContainer" ref="echartContainer" style="width:100%; height:400px"></div>

6,基本工作完成，初始化echarts实例

在mounted中初始化echarts实例

//option 是echarts配置对象
var charts = echarts.init(this.$refs.echartContainer);
charts.setOption(option);

kdemo.vue全部文件

<template>
  <div>
    <h1>echarts实现的k线图demo</h1>
    <div id="echartContainer" ref="echartContainer" style="width:100%; height:400px"></div>
  </div>
</template>
<script>
var echarts = require("echarts");
export default {
