我有以下脚本，我从inspect元素中提取了该脚本。我从mysql db中提取2个元素，这是日期时间和速度，我相应地格式化它。所有看起来都很好，因为我甚至打印了来自mysql的数组内容。它在这里给出了错误数据：[[2014-12-13 13:23,0 ],[2014-12-13 13:23,0 ],[2014-12-13 13:24,0 ],[2014-12-13 13:24,0 ],[2014-12-13 13:25,0 ....... Uncaught SyntaxError: Unexpected number
另一件事是如何让x轴根据我的数据显示动态范围和比例，这可能是几小时到几天。

日期格式需要生成为UTC ...
尝试......
$dateTime1 =
...应设置为UNIX_TIMESTAMP（需要乘以1000才能使此答案正确）。
另外，单独留下$speed和$data;你的PHP应该没问题。
x轴上的日期格式问题可能会以...
修复dateTimeLabelFormats: {
second: '%Y-%m-%d %H:%M',
minute: '%Y-%m-%d %H:%M',
hour: '%Y-%m-%d %H:%M',
day: '%Y-%m-%d %H:%M',
week: '%Y-%m-%d %H:%M',
month: '%Y-%m-%d %H:%M',
year: '%Y-%m-%d %H:%M'
}
...因为，Highcharts会选择您输入的最佳列表。如果您只想要这样，请尝试输入所有可能值的格式，有效地替换默认值。
使用旋转文字格式化日期时间格式的工作示例... http://jsfiddle.net/rfornal/827bfzr9/

就像与其他人共享一样，我注意到unix_timestamp应该是1000的倍数，以便在hightchart中正确显示。
