两组不规则区域的折线图echarts 折线配置项内容和展示

适合有两组数据的不规则区域, 如[低值, 高值], 折线的颜色填充不落在坐标轴上.

      var data1 = [220, 182, 191, 234, 290, 330, 310]; //高值
var data2 = [220, 170, 160, 200, 244, 240, 222]; //低值
var xBew = []; //差值
for (var i = 0; i < data1.length; i++) {
    xBew.push(data1[i] - data2[i]);
}

var item1 = [220, 212, 206, 205, 190, 250, 300]; //高值2
var item2 = [220, 205, 190, 180, 144, 165, 240]; //低值2
var xBew2 = []; //差值2
for (var i = 0; i < item1.length; i++) {
    xBew2.push(item1[i] - item2[i]);
}

var color1 = "#58bbb8";
var color2 = "#53d77e";
