在vue-cli项目中使用echarts

参考:https://www.cnblogs.com/Smiled/p/7686316.html

cnpm install echarts -S

 

  • 全局引入

  • main.js
    // 引入echarts
    import echarts from 'echarts'
    
    Vue.prototype.$echarts = echarts 
  • Hello.vue
    <div id="myChart" :style="{width: '300px', height: '300px'}"></div>
    复制代码
    export default {
      name: 'hello',
      data () {
        return {
          msg: 'Welcome to Your Vue.js App'
        }
      },
      mounted(){
        this.drawLine();
      },
      methods: {
        drawLine(){
            // 基于准备好的dom,初始化echarts实例
            let myChart = this.$echarts.init(document.getElementById('myChart'))
            // 绘制图表
            myChart.setOption({
                title: { text: '在Vue中使用echarts' },
                tooltip: {},
                xAxis: {
                    data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
                },
                yAxis: {},
                series: [{
                    name: '销量',
                    type: 'bar',
                    data: [5, 20, 36, 10, 10, 20]
                }]
            });
        }
      }
    }
    复制代码

    注意: 这里echarts初始化应在钩子函数mounted()中,这个钩子函数是在el 被新创建的 vm.$el 替换,并挂载到实例上去之后调用
