使用无点的连续曲线

Question

您可以使用mark=none；我个人会为此创建一个样式

\pgfplotsset{mystyle/.style={mark=none}}

可以用作

\addplot[mystyle]....

或者，如果您希望继承现有的样式，或者以其他方式创建的cycle list，那么您可以使用

\addplot+[mystyle]....

在下面的代码中，我使用了\addplot+

\documentclass{article}
\usepackage{pgfplots}

\pgfplotsset{compat=1.7}
\pgfplotsset{
    xticklabel={$\mathsf{\pgfmathprintnumber{\tick}}$},
    every axis/.append style={

        title style={font=\bfseries\sffamily}, 
        width=6.5cm,
        height=4.9cm
    }
}

\pgfplotsset{mystyle/.style={mark=none}}

如果你想创建自己的，cycle list那么你可以使用类似下面的内容

\pgfplotscreateplotcyclelist{mycyclelist}{%
color=red,mark=none,line width=1pt,\\%
color=blue,mark=none,line width=2pt,\\%
color=gray,mark=none,line width=3pt,\\%
color=purple,dashed,mark=none,line width=1pt,\\%
}

\pgfplotsset{
    xticklabel={$\mathsf{\pgfmathprintnumber{\tick}}$},
    every axis/.append style={
        font=\sffamily,
        title style={font=\bfseries\sffamily}, 
        width=6.5cm,
        height=4.9cm,
        cycle list name=mycyclelist,
    }
}

无论何时使用，\addplot+[mystyle]...它都会继承你指定的样式为了从cycle list；因此第一行将是red，第二行将是blue，第三行将是gray，第四行将是purple，（和dashed）并且第五行将返回到red。

请注意，使用\addplot[mystyle]...（不带+）将忽略cycle list。
