pgfplots 中的虚线段和图例中字体大小的变化

我有以下代码：

\documentclass[11pt]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{booktabs,siunitx}
\usepackage{pgfplots}
\pgfplotsset{width=10cm,compat=1.9}
%\usepgfplotslibrary{external}
%\tikzexternalize
\begin{center}
\begin{tikzpicture}
\begin{axis}[
    title={$x-t$ graph model of LAB 1},
    height=10cm,
    width=10.2cm,
    xlabel={time ($t$)},
    ylabel={position ($x$)},
    xmin=0, xmax=10,
    ymin=0, ymax=12,
    xtick={0,1,2,3,4,5,6,7,8,9,10},
    ytick={0,2,4,6,8,10,12},
    legend pos=south east,
    ymajorgrids=true,
    grid style=dashed,
    legend entries={$x$,$x^2$},
        legend style={
            at={(1.03,0.5)},
            anchor=west}
]
\addplot[
    color=blue,
    mark=square,
    ]
    coordinates {
    (0,0)(1.48,2)(2.76,4)(4.02,6)(5.22,8)(6.43,10)(7.76,12)
    };
\addplot[
    color=red,
    mark=square,
    ]
    coordinates {
    (0,0)(1.66,2)(3.21,4)(4.76,6)(6.32,8)(7.81,10)(9.47,12)
    };
\addplot[
    color=green,
    mark=square,
    ]
    coordinates {
    (0,12)(1.53,10)(2.94,8)(4.53,6)(5.95,4)(7.36,2)(8.83,0)
    };
\addplot[
    color=black,
    mark=square,
    ]
    coordinates {
    (0,12)(1.80,10)(3.46,8)(4.94,6)(6.49,4)(8.20,2)(9.85,0)
    };
\legend{Trail 1 (fast and $+$), Trail 2 (slow and $+$), Trail 3 (fast and $-$), Trail 4 (slow and $-$)}
\end{axis}
\end{tikzpicture}
\end{center}
\end{document}

生成以下图像：

图形

我想知道如何将上面的线段变成虚线（即黑色、蓝色、红色、绿色）。我想在其上添加一条最佳拟合线，因此我希望这些线是虚线。另外，如何更改图例的文本大小？我希望它稍微小一点，这样我就可以把图表放大。谢谢！

答案1

我做了以下改变：

  1. 添加every axis plot/.append style={line width=2pt,dotted}，使每行宽度为 2pt，采用虚线样式
  2. 添加mark options={solid}，这使得每个标记的线都是实线，否则它们将是虚线
  3. font=\scriptsize在 中添加，legend style以使图例文字变小。

此版本将线型局部应用于每个图。这是通过line width=2pt,dotted向每个图添加应用的选项来实现的\addplot。
