我一直在努力去除图中所示的这些箭头。看来我拥有的图表越多，这些箭头就越多。如果我不添加任何图表，它们就会完全消失。希望有人能帮助我！
这是我为该图表编写的代码：
\begin{tikzpicture}
\begin{axis}[
width=0.7\linewidth, % Scale the plot to \linewidth
xtick=data,
ymin=0,
ymax=1600,
%grid=major, % Display a grid
%grid style={dashed,gray!30}, % Set the style
xlabel=Gewicht $m$, % Set the labels
ylabel=Spannung $U$ Peak to Peak,
x unit=\si{\g}, % Set the respective units
y unit=mV,
]
\addplot+[mark=x, mark size=5, red, smooth]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=Reihe1, col sep=semicolon, only marks] {PeaktoPeakA.csv};
\addplot+[mark=x, mark size=5, blue, smooth]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=Reihe2, col sep=semicolon, only marks] {PeaktoPeakA.csv};
\addplot+[mark=x, mark size=5, green, smooth]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=Reihe3, col sep=semicolon, only marks] {PeaktoPeakA.csv};
\addplot+[mark=x,mark size=5, brown, smooth]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=Reihe4, col sep=semicolon, only marks] {PeaktoPeakA.csv};
\addplot+[mark=x,mark size=5, purple, smooth]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=Reihe5, col sep=semicolon, only marks] {PeaktoPeakA.csv};
\addplot+[black, dashed]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
table[x=Gewicht, y=b, col sep=semicolon, mark = none] {PeaktoPeakA.csv};
\node[label={y=0,0863x+312,65}] at (axis cs:7000,650) {};
%\addplot[blue]
% add a plot from table; you select the columns by using the actual name in the .csv file (on top)
%table[x=Membranabschnitt,y=160,col sep=semicolon, mark=none, dashed, y={create col/linear regression={y=160}}] % compute a linear regression from the input table {dreizeilentabelle.csv};
\end{axis}
\end{tikzpicture}

好的，我自己找到了错误。.csv 文件最初是在 excel 中制作的，因为其中一些文件有超过 1000 行。我将其从 Excel 保存为 .csv，并删除了所有 , 和 .，以便 Latex 可以理解它。我不知道如何或为什么，但通过使用这种方法，它会显示箭头。如果我只是复制 .csv 文件的内容，创建一个具有相同名称的新文件并粘贴相同的 .csv 内容，然后上传它，箭头就会消失。
