Question

我试图在折线图上显示注释。注释确实显示在页面加载上，但如果我放大Dygraph或调整页面大小，Dygraph不会重绘注释。奇怪的是，所有注释似乎都在初始加载时正确绘制。

这是确切的错误：

[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)

我的注释对象如下所示：

我的Dygraph初始化如下：

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

对此有何想法？这看起来像个错误吗？

Answer 1

你应该设置＆＃34; x＆＃34;注释的值，而不是Date对象。请参阅http://dygraphs.com/annotations.html。

添加带日期的注释时，Dygraph解析错误
