我想绘制带有说明的图表。但这只会生成忽略同一文档中其他文本的图表。我该怎么做？

答案1

如果我理解正确的话，你可能需要删除这些行

\usepackage[active,tightpage]{preview}  % For flowchart and Diagram
\PreviewEnvironment{tikzpicture}  % For flowchart and Diagram
\setlength\PreviewBorder{60pt}% to control size of the diagram, to reduce increase +ve value

这些行旨在生成紧凑的图片，不能用于常规文档。如果没有这些行，您的代码将：

\documentclass{article}
\usepackage{lipsum}
%\usepackage[latin1]{inputenc}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows} % For flowchart and Diagram

%%%<
\usepackage{verbatim}
%\usepackage[active,tightpage]{preview}  % For flowchart and Diagram
%\PreviewEnvironment{tikzpicture}  % For flowchart and Diagram
%\setlength\PreviewBorder{60pt}% to control size of the diagram, to reduce increase +ve value

笔记：

  1. 代替\tikzset已\tikzstyle被弃用的。
  2. 使用positioning库并使用below=of,right = of语法以获得更好的放置（而不是below of=）。
