横向柱形图echarts 柱状配置项内容和展示

主要是左侧白框的实现

      var nameArr = ["安徽省", "河南省", "浙江省", ];
var dataArr = [239, 181, 154, ];
var maxData = []; //背景按最大值
var minData = []; //左侧边框
for (let i = 0; i < dataArr.length; i++) {
    var item = dataArr[i];
    maxData.push(300 - item);
    minData.push(1);
}
var getSymbolData = (data) => {
    let arr = [];
    for (var i = 0; i < data.length; i++) {
        arr.push({
            value: data[i].value,
            symbolPosition: 'end'
        })
    }
    return arr;
}
