[JavaScript知识库]echarts 统计图 下钻 vue

echarts 统计图 使用下钻 vue

普通的 统计图

参考官网 echarts 官网

大部分常用的 已经都封装改好了 直接c v 完事

template>
                
  <div id="echart1"></div>   //放他的盒子 id 很重要


</template>

<script>
export default {
name: "",
data(){
return
},

mounted() {      
this.echarts();

},

methods: {
echarts（）{
var chartDom = document.getElementById('echart1');
var myChart = echarts.init(chartDom);
var option;

option = {
  xAxis: {
    type: 'category',
    data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [120, 200, 150, 80, 70, 110, 130],
      type: 'bar'
    }
  ]
};

option && myChart.setOption(option);
},

}
}
</script>

<style scoped>
//样式自己写去 

#echart1 {
height: 350px;
width: 800px;
margin: 0 auto;
}


</style>

想要钻取 就得给他添加点击 然后传入对应的数据调用方法

</script>

<style scoped>
//样式自己写去

</style>

对比一下 显而易见
