看起来问题与xAxis无关，无论dx得到什么值0

    chart.xAxis
  .showMaxMin(true)
  .tickFormat(function(d) {

    var dx = data[0].values[d] && data[0].values[d][0] || 0;
    return d3.time.format('%x')(new Date(dx))
  });

请有人帮忙解决这个问题。

Answer 1

没关系！我想出了答案。我认为问题在于解析日期的方式。

日期需要解析为毫秒

Date.parse( d.log_day )

nvD3 Lineplusbar图表工具提示显示错误的日期（12/31/1969）
