Flot高亮环偏移

Question

我正在绘制两个显示正常的时间序列行。

然后我打开了数据点的突出显示，这样我就可以提供工具提示并发现高亮环偏离实际数据点，我必须将鼠标悬停在数据点的左侧才能显示高亮环

我正在使用flot 0.8.3。

我的JS：

function gd(year, month, day) {
  return new Date(year, month - 1, day).getTime();
}
var hours_contractual = [
[gd(2017, 1, 1), 7], [gd(2017, 1, 2), 6], [gd(2017, 1, 3), 4], [gd(2017, 1, 4), 8],

这是CSS，我有一个边距应用于flot-base类，它应用于主canvas元素。工具提示继承了这个边距，从而改变了高亮环。

简单地删除flot-base类上的边距就解决了这个问题。
