我有一个柱状图，我需要画出图表的左、右和底线(x/y轴(，但需要省略顶部的
或者。。。
画一条白线盖住顶线。在Chrome中查看原始数据，我可以看到这个框是用<rect>绘制的。
是否可以使用JS来定位它，并获得x、y、宽度属性来绘制一条白线，或者将其删除并替换为3条黑线

您可以创建额外的yAxis，并使用lineWidth和offset属性来获得所需的结果：
xAxis: {
lineWidth: 3
},
yAxis: [{
lineWidth: 3,
offset: -2,
title: {
text: null
},
max: 4,
allowDecimals: false,
labels: {
enabled: true,
formatter: function() {
return this.value + ' %';
}
}
}, {
opposite: true,
title: {
text: ''
},
offset: -2,
lineWidth: 3,
}],
