TikZ 图片矩阵入口距离

Question

我在 tikz 图片中有一个矩阵（由 组成calendar）。我用 3 个矩形块将矩阵中的某些天数分开，但边缘重叠。如何防止边缘重叠？谢谢。 布卡普兹

\documentclass[10pt]{standalone}

\usepackage{tikz}

\usetikzlibrary{calendar,backgrounds}

\begin{document}

\begin{tikzpicture}
\matrix{
  \calendar (sep18) [dates=2018-09-01 to 2018-09-last,week list,month label above centered]; \\
};
\begin{scope}[on background layer]
 \draw[draw=none,fill=orange,opacity=0.3] (sep18-2018-09-17.north west) -- (sep18-2018-09-23.north east)
   -- (sep18-2018-09-30.south east) -- (sep18-2018-09-24.south west) -- cycle;
 \draw[draw=black] (sep18-2018-09-17.north west) rectangle (sep18-2018-09-21.south east);
 \draw[draw=black] (sep18-2018-09-24.north west) rectangle (sep18-2018-09-24.south east);
 \draw[draw=black] (sep18-2018-09-25.north west) rectangle (sep18-2018-09-27.south east);
\end{scope}
\end{tikzpicture}

\end{document} 

Answer 1

第一个选项，反复尝试day xshift直到day yshift找到正确的值以避免重叠：

\documentclass[10pt]{standalone}

\usepackage{tikz}

\usetikzlibrary{calendar,backgrounds, calc}

\begin{document}

\begin{tikzpicture}
\matrix{
  \calendar (sep18) [dates=2018-09-01 to 2018-09-last,week list,month label above centered, day xshift=4ex, day yshift=3.15ex]; \\
};
\begin{scope}[on background layer]
 \fill[orange,opacity=0.3] (sep18-2018-09-17.north west) rectangle (sep18-2018-09-30.south east);
 \draw[draw=black] (sep18-2018-09-17.north west) rectangle (sep18-2018-09-21.south east);
 \draw[draw=black] (sep18-2018-09-24.north west) rectangle (sep18-2018-09-24.south east);
 \draw[draw=black] (sep18-2018-09-25.north west) rectangle (sep18-2018-09-27.south east);
\end{scope}
\end{tikzpicture}

\end{document} 

第二种选择：根据日期之间的中间坐标绘制矩形，而不是重叠的锚点。

\documentclass[10pt]{standalone}

\usepackage{tikz}

\usetikzlibrary{calendar,backgrounds, calc}

\begin{document}

\begin{tikzpicture}
\matrix{
  \calendar (sep18) [dates=2018-09-01 to 2018-09-last,week list,month label above centered]; \\
};
\begin{scope}[on background layer]
 \fill[orange,opacity=0.3] (sep18-2018-09-17.north west) rectangle (sep18-2018-09-30.south east);

 \coordinate (aux1) at ($(sep18-2018-09-21.south east)!.5!(sep18-2018-09-28.north east)$);
 \coordinate (aux2) at ($(sep18-2018-09-21.south east)!.5!(sep18-2018-09-29.north west)$);
 \draw[draw=black] (sep18-2018-09-17.north west) rectangle (aux1|-aux2);

 \draw[draw=black] ($(sep18-2018-09-17.south west)!.5!(sep18-2018-09-24.north west)$) rectangle ($(sep18-2018-09-24.south east)!.5!(sep18-2018-09-25.south west)$) coordinate (aux3);

 \draw[draw=black] (aux3) rectangle (aux1|-aux2);

\end{scope}
\end{tikzpicture}

\end{document}
