echartsjs双X轴标签对应(非等分情况)，区县比例柱状图

使用的时候需要引入百度echartsjs.js文件

效果图

 

let data = {
    xData: ['花溪区', '南明区', '观山湖区', '钟山区', '六枝特区', '红花岗区', '汇川区', '遵义县', '西秀区', '平坝县', '玉屏县'],
    yData: [0.1, 0.15, 0.18, 0.25, 0.23, 0.32, 0.33, 0.36, 0.57, 0.72, 0.45]
}
/**
    双X轴标签对应，伪实现思路：
    底部的标签也是柱状图，对应包含的区域为上方X轴条数占总数的比例，设为宽度即可
