Time Gnuplot使用其他时间格式给出2列，而不是24列

我有下一个问题。我有一个像这样的数据文件

1412481600,304,0,0,0,304,0
1412485200,385,0,0,0,383,0
1412488800,332,0,0,0,331,0
1412492400,359,0,0,0,355,0

我已将格式更改为

08-11-2014-17:00,390,0,27,417
08-11-2014-18:00,474,0,0,474
08-11-2014-19:00,467,0,0,467
08-11-2014-20:00,687,0,0,687

我更改了gnuplotscript

一是,

set timemt x“%s”

到现在为止

set timemt x“%d-%m-%Y-%H:%m”

在新的情况下，gnuplot给了我两列，它们被覆盖了 与其他栏目。 我做错了什么，还是忘记了

这里是一个错误的例子；

绘图“有两个问题：首先，在所有情况下，您必须使用正确的时间格式
%d-%m-%Y-%H:%m
（在您发布的脚本中，您有一个小的
Y
，并且在stats命令中缺少一个破折号）

其次，为了正确解析日期，您必须在
using
语句中使用
时间列（1）
而不是
$1
。当您有时间戳时，它工作正常，因为它只是一个数字，但解析字符串失败。因此，您的完整脚本应该是

情节“到目前为止，你所做的似乎还不错。但是如果你不发布代码，就很难说代码出了什么问题。由于绘图的复杂性，您可以发布/尝试一个简单的示例，其中只绘制数据与时间的关系。一个猜测是：您用
，
分隔列，而gnuplot需要空格。您可以通过
设置数据文件分隔符“，”
Thanx来更改此设置。对于您的反应，我已将代码放在我的原始帖子中。该脚本仍然太复杂。我们不想调试您的整个脚本。如果没有任何数据，我们也无法复制。有一点可能是，对于
stats
命令，您使用的时间格式为
%d-%m-%y%H:%m
。这可能与您的常规时间相同，即
%d-%m-%Y-%H:%m
。很抱歉，这没有什么区别。我把数据文件的链接放在我的帖子里，希望你能在这里用它做点什么。我很想知道答案。提前（再次）谢谢。太好了，我就知道你会发现的。非常感谢您，您对gnuplot的了解是难以置信的！唉，我就知道你最终会放弃我。我希望我还在使用gnuplot——在去gnuplot gold的路上！恭喜：-）。@mgilson谢谢：）不过，要获得gnuplot金牌还有一段路要走。。。我半年前完成了论文，谁知道我能跟上gnuplot的发展多久；）
