如何在 tikz 中制作这个带有三角形和正方形的六角形网格矩形?

如何在 tikz 中制作这个带有三角形和正方形的六角形网格矩形?

我想用 tikz 制作这张图片。

我从此代码及其输出开始:

代码:

\documentclass{standalone}
\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{shapes.geometric,arrows.meta,calc,decorations.markings,math,arrows.meta}
\usetikzlibrary{plotmarks}
\usepackage{amsmath}

\begin{document}

\begin{tikzpicture}[x=7.5mm,y=4.34mm]
  %   some styles
  \tikzset{
  box/.style={
  regular polygon,
  regular polygon sides=6,
  minimum size=10mm,
  inner sep=0mm,
  outer sep=0mm,
  rotate=0,
  draw
}
}

  \foreach \i in {0,...,5} 
  \foreach \j in {0,...,5} {
  \node[box] at (2*\i,2*\j) {};
  \node[box] at (2*\i+1,2*\j+1) {};
}
  \draw[->] (-1,0) -- (13,0) node[anchor = north west] {$x$};
  \draw[->] (0,-1.5) -- (0,13) node[anchor = south east] {$y$};
    \node[draw=black,fill=black,rectangle,minimum width=0.2cm,minimum height=0.2cm,inner sep=0pt] at (4,4) {};
   \node[draw=black,fill=black,rectangle,minimum width=0.2cm,minimum height=0.2cm,inner sep=0pt] at (8,8) {};
   \node[draw=red,fill=red,isosceles triangle,isosceles triangle stretches,shape border rotate=90,minimum width=0.2cm,minimum height=0.2cm,inner sep=0pt] at (3,0) {};
   \node[draw=red,fill=red,isosceles triangle,isosceles triangle stretches,shape border rotate=90,minimum width=0.2cm,minimum height=0.2cm,inner sep=0pt] at (3,3) {};
   \node[draw=red,fill=red,isosceles triangle,isosceles triangle stretches,shape border rotate=90,minimum width=0.2cm,minimum height=0.2cm,inner sep=0pt] at (5,2) {};
\end{tikzpicture}
\end{document}

  1. 我无法生成 x 轴和 y 轴上的坐标(数字);
  2. 我无法将黑色方块和红色三角形放置在六边形的顶点上,如图所示;并且
  3. 我无法删除超出 x 轴和 y 轴的六边形。

感谢您的帮助。

注意:我在这个网站的某个地方找到了六边形网格的代码,但我记不清它的链接了。三角形和正方形取自这个链接https://tex.stackexchange.com/a/188535/80848

可以使用scope环境和\clip移除轴外的多边形部分来获得数字 3。我猜问题 1 和 2 都来自缩放。首先,x 轴和 y 轴的数量级为 100,这意味着如果我们想使用该比例绘制,我们需要设置例如x=0.1mm,y=0.1mm。上边和下边之间高度为 100 的六边形的宽度为 115.47(即 2*5/cos pi/6),每边的宽度为一半。由于多边形应以实数给出,因此缩放比例将其大小定为11.547mm(多边形的宽度、高度和大小以其角定义的圆的大小给出)。然后就可以开始计算正方形了:-)
