推荐答案

您要在x轴上设置valueFormatter选项:

You want to set the valueFormatter option on the x-axis: http://dygraphs.com/options.html#valueFormatter

例如，

new Dygraph(div, data, {
  axes: {
    x: {
      valueFormatter: function(ms) {
        return new Date(ms).strftime("%m/%d/%y %H:%M:%S");
      }
    }
  }
});

此处为实时示例: http://jsfiddle.net/eM2Mg/772/

值得注意的是，Date.strftime()不是标准的JavaScript方法:它是由strftime.js提供的，它包含在标准音标捆绑中.

It's worth noting that Date.strftime() is not a standard JavaScript method: it's provided by strftime.js, which is included in the standard dygraphs bundle.
