javascript - Flot 时间序列日期标签不正确

Question

我正在尝试使用 Flot 创建一个时间序列图来比较两个数据系列。在包含 jQuery、jquery.flot.js 和 jquery.flot.time.js 之后，我的代码如下所示:

$(function () {
  var d1 = {
    label: "Fall 2011",
    data: [
      [1296536400, 9],
      [1296622800, 23],
      [1296709200, 30],

  $.plot("#placeholder", [d1], {
    xaxis: {

    legend: {
      show: true,
      position: 'se'
    }
  });
});

这会生成图表:

请注意 x 轴标签不正确。 unix 时间戳范围从 2011 年 2 月 1 日到 2011 年 7 月 26 日。我尝试了各种“timeformat”和“minTickSize”选项，但无济于事。我究竟做错了什么？如何让标签显示整个数据范围的月份和日期名称？

Answer 1

您想将 UNIX 时间戳乘以 1000，以便将它们转换为适合 Javascript 的格式。
