我是一名正在写硕士论文的学生，希望能够使用 pgfplots 在 LaTeX 中绘制眼图。我有一个 csv 文件，其中包含“时间、电压”格式的眼图数据。主要问题是我不知道如何将使用的数据片段的起始时间值移至零以进行绘制。如果这个问题解决了，我可以用一个简单的 for 循环绘制图表。我现在使用的代码如下所示：
\usepackage{pgfplots} % <-- in preamble
\pgfplotsset{compat=newest} % <-- in preamble
\newenvironment{ploteye}[2]{
\begin{tikzpicture}
\begin{axis}[
xlabel=Time (s), % \hertz requires SIunits
ylabel= Voltage (V),
grid=both,
minor grid style={gray!25},
major grid style={gray!25},
width=1\linewidth,
height=0.5\linewidth,
xmin = 0.00000001,
xmax = 0.0000000108,
ymin = #1,
ymax = #2,
no marks]
}
{
\end{axis}
\end{tikzpicture}
}
\begin{ploteye}{0.6}{0.75}
\addplot[red, thick, restrict x to domain=0.00000001:0.0000000108] table [x=t, y=V, col sep=comma] {TESTEYE.csv};
\addplot[red, thick, restrict x to domain=0.0000000108:0.0000000116] table [x=t, y=V, col sep=comma] {TESTEYE.csv};
\end{ploteye}
我无法包含 csv 文件，但这里有一个可用的部分：

简而言之，我的问题是，如何绘制 csvfile 的一部分，并在时间值上进行调整？如果有更好的绘制方法，我很想听听。
多谢

答案1
所以 --- 请注意我上面的评论，下次尝试将您的问题减少到最低限度，以便帮助我们帮助您。
我在以下示例中所做的是：
csv为了示例，创建一个 8 行文件；将其添加到使用环境的示例代码中
filecontent以获得单个紧凑代码；它将创建（并覆盖，小心！）文件TEST.csv并使用它；删除新环境的定义和嵌套，因为它与问题无关；
现在，如果有人想添加内容或者解决我的问题，只需复制、粘贴和编译即可。
如果你完成了上述操作，你就会得到答案很多早些时候…
解决方案是使用x expr表参数选项，让您对表值应用数学运算。
\begin{filecontents}[overwrite]{TEST.csv}
t, V
0, 1
1, 2
2, 3
3, 4
4, 3
5, 2
6, 1
\end{filecontents}
\documentclass[border=10pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usepackage{pgfplots}\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}[]
\begin{axis}[
xlabel=Time (s), % \hertz requires SIunits
ylabel= Voltage (V),
grid=both,
minor grid style={gray!25},
major grid style={gray!25},
width=1\linewidth,
height=0.5\linewidth,
no marks]
\addplot[red, thick, ] table [x=t, y=V, col sep=comma] {TEST.csv};
\addplot[black, thick, ]
table [x expr=\thisrow{t}+1, y=V, col sep=comma] {TEST.csv};
\end{axis}
\end{tikzpicture}
\end{document}
