使用 foreach 在 tikz 中绘制点

Question

我有以下代码：

\documentclass{standalone}
\usepackage[portuguese, shorthands=off]{babel} 
\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usepackage{xfp}
\usepackage{pgfplots}
\usepackage{tkz-euclide}

\begin{document}


\foreach \i in {1,...,5}{
\foreach \j in {1,...,5}{
\begin{tikzpicture}
\clip (-4.,-4.) rectangle (4.,4.);
\draw[help lines,step=1,densely dotted, gray!80] (-3,-3) grid (3,3);
\draw[->,-latex',line width=1pt] (-3,0) -- (3,0) node[right]{$x$};
\draw[->,-latex',line width=1pt] (0,-3) -- (0,3) node[above]{$y$};

\foreach \a in {1,...,\i}{
    \foreach \b in {1,...,\j}{
        \draw[fill=blue,draw=blue] ({\a-3},{\b-3}) circle (1pt);
    }
}
\end{tikzpicture}
}
}

\end{document}

我的目的是为插入的每个点创建一个不同的图形。我想按以下顺序逐一绘制这些点：

(-2,-2), (-2,-1) .... (-2,2)-> 下一个 (-1,-2), (-1,-1),....,(-1,2)-> 下一个 (0,-2), (0,-1),...,(0,2)-> 下一个 ..... (2,-2), (2,-1),...,(2,2)。

在每个新图形中，我想保留上一次迭代中生成的点。

我怎样才能调整我的代码来实现这一点？

%\usepackage[utf8]{inputenc}
\usepackage{tikz}
\usetikzlibrary{arrows}
%\usepackage{xfp}
%\usepackage{pgfplots}
%\usepackage{tkz-euclide}

\begin{document}


\foreach \i in {0,...,24}{
\begin{tikzpicture}
\clip (-4.,-4.) rectangle (4.,4.);
\draw[help lines,step=1,densely dotted, gray!80] (-3,-3) grid (3,3);
\draw[->,-latex',line width=1pt] (-3,0) -- (3,0) node[right]{$x$};
\draw[->,-latex',line width=1pt] (0,-3) -- (0,3) node[above]{$y$};

\foreach \a in {0,...,\i}
        \draw[fill=blue,draw=blue] ({int(\a/5)-2},{mod(\a,5)-2}) circle (1pt);
\end{tikzpicture}
}
