如何在 tikz 中產生帶有三角形和正方形的六邊形網格矩形？

我想用 tikz 製作這張圖。

我從這段程式碼及其輸出開始：

代碼：

\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. 我無法產生 x 軸和 y 軸的座標（數字）；
  2. 我無法將黑色正方形和紅色三角形放置在六邊形的頂點處，如圖所示；和
  3. 我無法刪除超出 x 軸和 y 軸的六邊形。

感謝您的幫助。

注意。我在這個網站的某個地方找到了六角網格的程式碼，但我不記得它的連結。三角形和正方形取自此鏈接https://tex.stackexchange.com/a/188535/80848

scope可以使用環境以及\clip刪除軸外的多邊形部分來獲得數字 3 。我猜問題1和2都來自於縮放。首先，x 和 y 軸的大小約為 100 秒，這意味著如果我們想使用該比例進行繪製，我們需要設定例如x=0.1mm,y=0.1mm。上邊和下邊之間的高度為 100 的六邊形的寬度為 115.47（即 2*5/cos pi/6），每條邊都是寬度的一半。由於多邊形應該以實際尺寸給出，因此縮放比例將其尺寸給出為11.547mm（多邊形的寬度、高度和尺寸以由其角定義的圓的尺寸給出）。然後就可以開始數方塊了:-)
