绘制带框的直方图

Question

我尝试绘制带有方框的直方图。使用 pgfplots 绘制直方图似乎非常简单，而且我确信我想要做的并不困难，但我找不到一个很好的例子。因此问题是：我如何手工绘制出像这里这样的图形？

Answer 1

你可以直接画出来tikz而不需要pgfplot

\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
  \newcommand\rectsep{3pt}
  \newcommand\rectbox[6]{%{x}{y}{dx}{dy}{Label}{color}
    \draw[fill=#6] (#1cm+\rectsep,#2cm+\rectsep) rectangle node{#5} +(#3cm-2*\rectsep,#4cm-2*\rectsep);}
  \draw[->](0,0)--(4,0)node[anchor=north west]{$V_1$};
  \draw[->](0,0)--(0,4)node[anchor=south east]{$V_2$};
  \foreach \Tick in {1,2,3}{
    \draw (\Tick,0)-- +(0,-0.2) node[below]{$\Tick00$};
    \draw[thin,gray] (\Tick,0)-- +(0,4);
    \draw (0,\Tick)-- +(-0.2,0) node[left]{$\Tick00$};
    \draw[thin,gray] (0,\Tick)-- +(4,0);
  }
  \begin{scope}
    \clip (0,0) rectangle (4.7,4.7);
    \rectbox{1}{1}{1}{2}{1}{red!40}
    \rectbox{1}{3}{1}{2}{2}{blue!40}
    \rectbox{2}{1}{1}{1}{3}{green!40}
    \rectbox{2}{2}{1}{1}{4}{yellow!40}
    \rectbox{2}{3}{1}{2}{5}{magenta!40}
    \rectbox{3}{2}{2}{1}{6}{cyan!40}
    \rectbox{3}{3}{2}{2}{7}{gray!40}
  \end{scope}
\end{tikzpicture}
\end{document}
