我正在尝试使用画布覆盖在烛台图表上绘制一条水平线，我得到一个错误：对象不支持属性或方法'series_u2p'错误？
任何想法可能是什么原因？

答案 0 :(得分：2)
块图表遇到了同样的问题，但看起来它并不依赖于图表类型。
如果轴已设置为
seriesDefaults: {
yaxis: 'y2axis'
}
要使叠加层起作用，您还需要为叠加层对象指定它，例如：
canvasOverlay: {
show: true,
objects: [
{verticalLine: {
yaxis: 'y2axis', // <--- specify axis
x: 0,
lineWidth: 1,
color: 'rgb(255, 0, 0)',
shadow: false
}}
]
}
答案 1 :(得分：0)
我对条形图有同样的问题。
问题似乎来自以下选项
seriesDefaults: {
yaxis: 'y2axis'
}
尝试发表评论，看看会发生什么。
无论如何，我不知道如何真正解决问题。 jqplot库中可能存在故障。
希望这有帮助！
