我正在尝试使用 pgfplot 绘制表中的三列。
我一直在寻找，但找到的解决方案似乎对我不起作用。到目前为止，无论我做什么都无济于事，我只得到一条带有勾号的线（我不想要）。
我已经检查过（仅举几个地方）
这是当前的代码：
\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}[
title=My first gaph,
xlabel={$\text{Ár}$},
ylabel={$\text{Skerðingar}$},
]
\addplot+[] table {test.txt};
\foreach \column in {1,...,3}{
\addplot+[] table {test.txt};}
\end{axis}
\end{tikzpicture}
\end{figure}
我也尝试过
\begin{figure}
\centering
\begin{tikzpicture}
\begin{axis}[
title=My first gaph,
xlabel={$\text{Ár}$},
ylabel={$\text{Skerðingar}$},
]
\addplot+[blue] table[meta=Steady] {test.txt};
\addplot+[red] table[meta=Incr] {test.txt};
\end{axis}
\end{tikzpicture}
\end{figure}
到目前为止我只能拍这张照片
但我正在尝试做类似的事情
我确信我能够修复年份并为每行添加相应的图例。我确实将每列的名称更改为英文，以防止出现我的语言中的特殊字符错误。
最后，我想绘制的表格

我很确定，如果我掌握了 pgfplot，我的论文会写得更快（昨天才学到，所以请耐心等待）。文档对我没有太大帮助，但也许我误解了它。

我使用了比黄色更好的颜色“Goldenrod”，如果您想使用它，请记住在之前xcolor使用该选项加载包，否则您将遇到错误。[dvipsnames]pgfplots
