Question

我试图在Dygraph中绘制一些来自OpenTSDB的数据。我有查询工作，我可以绘制数据。但是，当我尝试设置x滚动条属性（如下所示）时，我得到：

Uncaught TypeError: undefined is not a function  dygraph-combined.js:2
Dygraph.numberValueFormatter                     dygraph-combined.js:2
Dygraph.numberAxisLabelFormatter                 dygraph-combined.js:2
Dygraph.getDateAxis                              dygraph-combined.js:2
Dygraph.dateTicker                               dygraph-combined.js:2
Dygraph.addXTicks_                               dygraph-combined.js:2
Dygraph.drawGraph_                               dygraph-combined.js:2
Dygraph.predraw_                                 dygraph-combined.js:2
Dygraph.start_                                   dygraph-combined.js:2
Dygraph.__init__                                 dygraph-combined.js:2
Dygraph                                          dygraph-combined.js:2

我使用的代码是：

new Dygraph(document.getElementById("graphdiv2"), obj[0].dps, {
  labels: [ "Date", "Fuel Level" ],
  ylabel: 'Fuel Level', 
  xlabel: 'Date',
  axes: {
    x: {
      valueFormatter: Dygraph.dateString_,
      ticker: Dygraph.dateTicker }
    },
  xValueParser: function(x) { return parseInt(x); }
});

如果我取出ticker: Dygraph.dateTicker选项，那么图表就会完美地绘制，当我将鼠标悬停在图表上时显示的值是正确的日期和时间，但是刻度值是unix时间戳。这是什么问题？

Dygraph自动收报机问题 - 无法获取日期
