Overleaf Latex 中条形图的填充颜色列表是什么？如何更改条形图的默认颜色？

Question

默认颜色与 overleaf 无关，但它们存储在循环列表中。的相关循环列表ybar（与相同xbar）可以在手册 v1.16 第 86 页找到，

您可以将其更改为例如

\documentclass{article}
\usepackage[margin=0.5in]{geometry}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage[dvipsnames]{xcolor}
\usepackage{pgfplots}
\pgfplotsset{width=10cm,compat=1.16}
\pgfplotsset{
/pgfplots/bar cycle list/.style={/pgfplots/cycle list={
{OliveGreen,fill=OliveGreen!30!white,mark=none},
{Plum,fill=Plum!30!white,mark=none},
{cyan!60!black,fill=cyan!30!white,mark=none},
{black,fill=gray,mark=none},
},
},
}
\begin{document}

\begin{tikzpicture}
\pgfplotsforeachungrouped \X in {1,...,9}
{\ifnum\X=1
\edef\mylst{Testing1}
\else
\edef\mylst{\mylst,Testing\X}
\fi}
\begin{axis}[symbolic x coords/.expanded=\mylst,
    ylabel=Number,
    enlargelimits=0.05,
    x tick label style={anchor=north west,rotate=-30},
    legend style={at={(0.5,-0.2)},
    anchor=north,legend columns=-1},
    ybar,
]
\addplot 
    coordinates {(Testing1,9) (Testing2,4)
         (Testing3,4) (Testing4,1) (Testing5,1) (Testing6,8) (Testing7,1) (Testing8,1) (Testing9,1)};
\addplot 
    coordinates {(Testing1,3) (Testing2,5)
         (Testing3,5) (Testing4,4) (Testing5,5) (Testing6,7) (Testing7,0) (Testing8,0) (Testing9,0)};
\legend{Series 1, Series2}
\end{axis}
\end{tikzpicture}
\end{document}

在这里我加载了获取您喜欢的颜色的选项，您也可以使用xcolor之前因为它无论如何都会加载。dvipsnames\PassOptionsToPackage{dvipsnames}{xcolor}\usepackage{pgfplots}xcolor

或者，您可以将选项直接传递给\addplot：

\documentclass{article}
\usepackage[margin=0.5in]{geometry}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage[dvipsnames]{xcolor}
\usepackage{pgfplots}
\pgfplotsset{width=10cm,compat=1.16}
\begin{document}

\begin{tikzpicture}
\pgfplotsforeachungrouped \X in {1,...,9}
{\ifnum\X=1
\edef\mylst{Testing1}
\else
\edef\mylst{\mylst,Testing\X}
\fi}
\begin{axis}[symbolic x coords/.expanded=\mylst,
    ylabel=Number,
    enlargelimits=0.05,
    x tick label style={anchor=north west,rotate=-30},
    legend style={at={(0.5,-0.2)},
    anchor=north,legend columns=-1},
    ybar,
]
\addplot[fill=ForestGreen!30,draw=ForestGreen] 
    coordinates {(Testing1,9) (Testing2,4)
         (Testing3,4) (Testing4,1) (Testing5,1) (Testing6,8) (Testing7,1) (Testing8,1) (Testing9,1)};
\addplot[fill=RoyalPurple!30,draw=RoyalPurple]  
    coordinates {(Testing1,3) (Testing2,5)
         (Testing3,5) (Testing4,4) (Testing5,5) (Testing6,7) (Testing7,0) (Testing8,0) (Testing9,0)};
\legend{Series 1, Series2}
\end{axis}
\end{tikzpicture}
\end{document}

当然，您可以使用列表中的任意颜色。
