如果指定了 xmin/xmax，则 Dateplot 不起作用

如果指定了 xmin/xmax，则 Dateplot 不起作用

这是一个简单的数据文件data.csv：

Time,Value
"2017-01-31 12:51:05",500
"2017-01-31 12:51:05",820
"2017-01-31 13:48:14",820
"2017-01-31 13:48:14",500

以下是它的简单情节：

\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{dateplot}
\pgfplotsset{compat=newest}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
    date coordinates in = x,
    set layers,
    every axis plot/.append style={on layer=pre main},
    xticklabel = {\hour:\minute},
    x tick label style = {align=center},
    xlabel = X, 
    ylabel = Y,
    ymin = 500.0,
    ymax = 820.0
]

\addplot [color = black, fill = black, opacity = 0.2, draw opacity = 0] table [y=Value, col sep = comma]{data.csv};

\end{axis}
\end{tikzpicture}
\end{document}

这会按照你期望的方式工作：

我想指定xmin，xmax和xtick（显然需要添加date ZERO）：

\begin{axis}[
    date coordinates in = x,
    set layers,
    every axis plot/.append style={on layer=pre main},
    xticklabel = {\hour:\minute},
    x tick label style = {align=center},
    date ZERO = 2017-01-31 08:00,
    xtick = {2017-01-31 09:30,2017-01-31 11:30,2017-01-31 13:30,2017-01-31 15:30},
    xmin = 2017-01-31 08:00,
    xmax = 2017-01-31 17:00,
    xlabel = X, 
    ylabel = Y,
    ymin = 500.0,
    ymax = 820.0
]

现在我得到以下内容：

Error: ! Dimension too large.<recently read> \pgf@xx \end{axis}
       ! Dimension too large.\pgf@process #1->{#1\global\pgf@x = \pgf@x\global \pgf@y = \pgf@y }\end{axis}
       …

但是当我评论时\addplot，我得到：

哪个是正确的画布。为什么？？？

答案1

似乎与日期/时间周围的引号有关data.txt，删除它们，你会得到

底部代码输出

加上引号，\year不知怎么就变成了 8215，而不是 2017。设置一下xticklabel = {\year-\month-\day--\hour:\minute}, x tick label style = {align=center,rotate=45}就可以看到：
