},

methods: {

treeData() {

var dom = document.getElementById("container");

var myChart = echarts.init(dom);

//  颜色设定 不同颜色寓意不同权重

var fatherColor = 'green';

var midColor = 'rgb(193, 92, 31)';

var smallColor = 'rgb(247, 203, 174)';

var option;

// 新能源汽车

let swyyQ = {

"name": "新能源汽车",

}

// 获取网页宽度 设置树形条目实体宽高度

let width = document.body.scrollWidth;

let widthSize = 0.039 * width;

if (widthSize > 36) {

widthSize = 36;

}

let heightSize = widthSize * 2.2;

myChart.setOption(

(option = {

tooltip: {

trigger: 'item',

triggerOn: 'mousemove'

},

series: [{

type: 'tree',

data: [data],

left: '2%',

right: '2%',

top: '8%',

bottom: '20%',

symbol: 'square',

symbolSize: [widthSize, heightSize],

orient: 'vertical',

expandAndCollapse: true,

initialTreeDepth: 2,

label: {
