Dygraph解析錯誤時添加註釋日期

我試圖讓註釋顯示在一個線圖上。註釋在頁面加載時顯示，但如果我放大Dygraph或調整頁面大小，Dygraph不會重新繪製註釋。奇怪的是，所有註釋似乎都在初始加載時正確繪製。Dygraph解析錯誤時添加註釋日期

這裏是確切的錯誤：

[Error] TypeError: 'undefined' is not a function (evaluating 'a.search("-")') 
    dateParser (dygraph-combined.js, line 2) 
    setAnnotations (dygraph-combined.js, line 2) 
    setAnnotations (dygraph-combined.js, line 2) 
    (anonymous function) (viewsreport.aspx, line 408) 
    ready (dygraph-combined.js, line 2) 
    drawChart (viewsreport.aspx, line 407)

我的註釋對象是這樣的：

我Dygraph是這樣的初始化：

var chart = new Dygraph(document.getElementById(timeLineDiv), data, {displayAnnotations: true}); 
      chart.ready(function() { 
       chart.setAnnotations(annotations); 
      });

對此有何想法？這看起來像一個錯誤？

您應該將註釋的「x」值設置爲字符串，而不是Date對象。見http://dygraphs.com/annotations.html。

是的，這似乎工作。只做了一個toString（），它解決了這個問題，並且大部分都是正確的（註釋字母不能正確顯示，但這是另一個問題......）。 – omniron
