在章节样式里使用tikz mindmap图

代码如下：

%\documentclass[10pt,krantz2]{krantz}
\documentclass[10pt]{book}
%\usepackage{sfheaders}        %% Chap/Sec headers in Helvetica;
\usepackage{graphicx}         %% well, its about graphics
\usepackage{blindtext}

\usepackage[paperwidth=7in,paperheight=10in]{geometry}

\usepackage{tikz}
\usetikzlibrary{mindmap,backgrounds}
\colorlet{col1}{teal}        %% Part I color
\colorlet{col2}{olive}       %% Part II
\colorlet{col3}{orange}      %% Part III

% local chapter commands
\newcommand{\chapterprelude}[1]{%
\textsf{#1}
\par\noindent
\rule{\textwidth}{0.4pt}
}
\newcommand{\hard}{$^\star$\xspace}

\setcounter{chapter}{2} % one less than chapter number

\usepackage{titlesec}

\newcommand{\chaptitle}[1]{%
\begin{tikzpicture}
  \node[fill=col1!20,inner sep=6pt,text width=\dimexpr\linewidth-12pt\relax] {#1};
\end{tikzpicture}
}

\titleformat{\chapter}[display]
{\normalfont\huge\bfseries\sffamily}{\scalebox{3}{\thechapter}}{25pt}{\Huge\chaptitle}
\titlespacing*{\chapter} {0pt}{110pt}{20pt}

\newsavebox{\mybox}

Discrete data often follow various theoretical probability models.
Graphic displays are used to visualize goodness of fit,
to diagnose an appropriate model, and determine the impact of
individual observations on estimated parameters.
