$（文档）.ready（函数（）{

var r=“日期、抛物线、直线、另一条直线、正弦波\n”；
对于（var i=1；i很抱歉，我第一次误解了您的问题。它现在应该将您的CSV数据绘制成图形，然后突出显示指定的日期范围。（您会注意到整个图形为黄色-这是因为突出显示开始和突出显示结束比您的数据集大）
如果你想看到它运行。基本上我所做的就是从你提到的例子中复制underlayCallback
函数。然后我调整它以处理日期
这是由
var highlight_start = new Date('2015/01/01');
var highlight_end = new Date('2015/10/28');
然后我将它们输入underlayCallback
，用于确定canvas.fillRect
函数的坐标
正如我前面提到的，这些数据范围比您的数据集大。不管怎样，您需要做的就是调整这些数据字符串的格式样式，以获得所需的结果。FYI您的示例链接已断开，但这是我再次更新我的答案的真实链接。这应该是您现在正在寻找的。另外一个问题：我如何才能添加注释？->添加：g.setAnnotations（[{series:“Temperature”，x:“2008-05-08”，shortText:“L”，text:“Coldest Day”}]）；不起作用…@MartinGöpfert我会打开一个新的问题，因为这是一个全新的问题。
var highlight_start = new Date('2015/01/01');
var highlight_end = new Date('2015/10/28');
