MADE A PIE 之动态树形图

MADE A PIE api地址

他那个api里的代码可以直接拿过来用，只是他没有写怎么使用

使用时我发现如果节点太多会导致节点名称重叠，所以我在他这个基础之上加了一个放大缩小和随意拖动（dragstart，dragend，flTop，flLeft），如果对拖拽有需求可以看我之前文章

 <div
      class="app-wrapper"
      id="myChart"
      style="position: absolute;"
      :style="'width:' + flWidth + 'px;height:' + flHeight + 'px;top:' + flTop + 'px;left:' + flLeft + 'px'"
      draggable="true"
      @dragstart="dragstart1($event)"
      @dragend.stop="dragend($event)"
    >
    </div>

通过获取id使用

      var chartDom = document.getElementById('myChart');
      myChart = that.$echarts.init(chartDom);
      myChart.setOption(option);

在官方文档里使用的逻辑直接复制就可以正常使用了（option是初始化canvas数据）

下面是我是用的整个代码：

我在传了两个值（如果不需要直接改成固定值）

1.basicstateheight：画布高度

2.basicstateWidth：画布宽度

画布使用属性：（字段都是代码里的，可以直接搜索）

1.symbolSize：图标宽高

2.colork：线的颜色

3.source：标题内容

4.textStyle：标题样式

5.target：对应连线的点，和下一级的名字对应

6.links：包括线的颜色，流水线的颜色（link，line）

<template>
  <div
    ref="body"
    style="width: 100%;height: 100%;"
  >

    
    <div
      class="app-wrapper"
      id="myChart"
      style="position: absolute;"
      :style="'width:' + flWidth + 'px;height:' + flHeight + 'px;top:' + flTop + 'px;left:' + flLeft + 'px'"
      draggable="true"
      @dragstart="dragstart1($event)"
      @dragend.stop="dragend($event)"
    >
    </div>
