显示相同值的d3时间格式x轴

Question

我试图沿着d3.js图的x轴绘制日期。然而，当应该有不同的值时，我会在a轴上重复相同的值。

我将日期格式化如下：

var format = d3.time.format('%m/%d/%Y %H:%M').parse;

然后直接在数据调用之后：

data.forEach(function(d) {
    d.timestamp = format(d.timestamp); // d.timestamp is from the data
});

然后将域设置如下：

var xScale = d3.time.scale().range([0, width]);
xScale.domain([d3.min(data, xValue), d3.max(data, xValue)]);

正如您在图像中看到的，下面的值是沿着x轴绘制的。

我这样做对吗？

感谢Lars Kotthoff的帮助，他指出我使用的是d3的一个古老版本。简单地更改为更新版本的d3解决了我的问题。他通过聊天回答了这个问题，所以没有直接的回答来标记为正确的答案。但他解决了这个问题。
