图例位置问题

Question

我一直在使用 tikz 包来绘制我的图表。当我想描述图中的每个图表时，我会使用“图例条目”，使用“图例位置”我可以管理描述图表的框。但现在我想将一些图例条目放在不同的位置，如我所附的图所示。这是我想在其中进行更改的代码。

\documentclass[12 pt]{article} 
\usepackage{times,bm}
\usepackage[affil-it,]{authblk}

\tikzset{  
    level/.style   = { thick, },
    connect/.style = { dotted, red   },
    notice/.style  = { draw, rectangle callout, callout relative pointer=        {#1} },
    label/.style   = { text width=2cm }}

        \addplot [thick, cyan]          table {sdg13.dat};
        \addplot [thick, JungleGreen]   table {sdg14.dat};

这段代码给了我

但我想

我该如何解决呢？

像这样：

由于我没有带有绘图数据的表格，因此我只用坐标模拟了其中三个。这足以了解如何在图表中将标签添加到曲线中。

\documentclass[12 pt]{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.16}

\begin{document}
    \begin{figure}
    \centering
\begin{tikzpicture}[scale=2]
    \begin{axis}[
        width=70mm,             % new
        xlabel={$\varepsilon$},
        ylabel={$E$},
        ymin=0, ymax=6,         % new, needed for my coordinates, can be omitted
        axis y line=left,       % new
        y axis line style={-},  % new
        % no marks,             % use in the case if you not like to have marks on curves
        clip=false,             % new
        font=\footnotesize      % new, but is not important
                ]
        \addplot +[thick]   coordinates {(0,3) (2,5)} node[right] {$1/2[400]$};
        \addplot +[thick]   coordinates {(0,2) (2,4)} node[right] {$1/2[411]$};
        \addplot +[thick]   coordinates {(0,1) (2,3)} node[right] {$3/2[402]$};
    \end{axis}
\end{tikzpicture}
    \end{figure}
