我正在尝试根据以下数据从表格中绘制图表：
DIM AVRG1 MAX1 MIN1 AVRG2 MAX2 MIN2
所以我想在图表中画 6 条线：
- 2 表示
- 2 表示最大值
- 2 表示最小值
此外，我想用更深的颜色（如蓝色和红色）来“标记”平均值，并赋予另外两种不太强烈的颜色，例如青色或橙色。
所以我包括
\usepackage{tikz}
\usetikzlibrary{graphdrawing}
\usetikzlibrary{graphs}
让 tikz 负责加载 xcolor 我传递给它以下选项：
\PassOptionsToPackage{usenames,dvipsnames}{xcolor}
如果我尝试单独加载 xcolor 我会收到错误，但这种方式却可以正常工作。
然后我通过以下方式从文件中获取值：
\begin{tikzpicture}
\begin{axis}[width=\linewidth, xmin=0, xmax=8192, ymin=0]
\addplot [thick, blue] table [mark=none, y=AVRG1, x=DIM]{time1-CPU.data};
\addplot [small, cyan]table [mark=none, y=MAX1, x=DIM]{time1-CPU.data};
\end{axis}
\end{tikzpicture}
这确实有效，因为青色在 tikz [2] 中。但是，假设我想使用 xcolor [1] 中的 Cerulean 而不是青色，那么我会收到以下错误：
Package pgfkeys Error: I do not know the key '/tikz/Cerulean' and I am going to ignore it. Perhaps you misspelled it
我该如何让它工作？谢谢！

我把所有包裹都留在里面，因为我不知道它们是否会与另一个包裹发生冲突（？）。
编译后得到：
Package xcolor Error: Undefined color `Cerulean'.
和
Package xcolor Error: Undefined color `tikz@color'.
答案1
Cerulean下面是一个可以很好地显示效果的示例：
代码：
\PassOptionsToPackage{usenames,dvipsnames}{xcolor}
\documentclass[border=2pt]{standalone}
\usepackage{pgfplots}
\begin{document}
\noindent
\begin{tikzpicture}
\begin{axis}
\addplot [thick, red, mark=none] {x+3};
\addplot [thick, Cerulean, mark=none] {-2*x-4};
\end{axis}
\end{tikzpicture}
\end{document}
答案2
您可以在开始时定义自己的颜色
\definecolor{Blue}{rgb}{0.0,0.0,0.7}
\definecolor{Red}{rgb}{0.7,0.0,0.0}
\definecolor{Green}{rgb}{0.0,0.5,0.0}
\definecolor{Gray}{gray}{0.85}
\definecolor{LightCyan}{rgb}{0.88,1,1}
\definecolor{White}{rgb}{1,1,1}
