如何删除指向 0 的箭头？

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！

在此处输入图片描述

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。
