[Tex/LaTex] Pgfplots: Limiting grid lines or extending arrowhead of x-y axis in simple Cartesian plane

pgfplotstikz-pgf

I am attempting to create a simple Cartesian plane using pgfplots, where the positive ends of the x and y-axis extend slightly past the square grid. So far, what I have is as follows:

\documentclass{article}

\usepackage{tikz, pgfplots}

\begin{document}
\begin{center}
    \begin{tikzpicture}
        \begin{axis}[
            axis lines=middle,
            axis line style=->,
            xmin=-10,xmax=10,
            ymin=-10,ymax=10,
            grid=both,
            grid style={draw=gray!25},
            xtick={-10, -8, ..., 10}, xtick style={yshift=-0.5ex},
            ytick={-10, -8, ..., 10}, ytick style={xshift=-0.5ex},
            yticklabel style={xshift=-0.5ex},
            minor tick num=1,
            minor tick length=0.5ex,
            minor x tick style={yshift=0.25ex}, minor y tick style={xshift=0.25ex},
        ]
        \end{axis}
    \end{tikzpicture}
\end{center}
\end{document}

For reference, here is the template I'm attempting to replicate.

By extending the xmax/ymax values, the grid lines by default extend to these values. Would anyone have any suggestions on either limiting the grid length or extending the positive axis ends?

Welcome! You can use shorten and use a negative distance.

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\begin{document}
\begin{center}
    \begin{tikzpicture}
        \begin{axis}[
            axis lines=middle,
            axis line style={-stealth,shorten >=-3mm},
            xmin=-10,xmax=10,
            ymin=-10,ymax=10,
            grid=both,
            grid style={draw=gray!25},
            xtick={-10, -8, ..., 10}, xtick style={yshift=-0.5ex},
            ytick={-10, -8, ..., 10}, ytick style={xshift=-0.5ex},
            yticklabel style={xshift=-0.5ex},
            minor tick num=1,
            minor tick length=0.5ex,
            minor x tick style={yshift=0.25ex}, minor y tick style={xshift=0.25ex},
        ]
        \end{axis}
    \end{tikzpicture}
\end{center}
\end{document}

Or with x and y labels.

\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.17}
\begin{document}
\begin{center}
    \begin{tikzpicture}
        \begin{axis}[
            axis lines=middle,
            axis line style={-stealth,shorten >=-3mm},
            xmin=-10,xmax=10,
            ymin=-10,ymax=10,
            xlabel=$x$,
            every axis x label/.style={at={(xticklabel cs:1,0)},
            yshift=1.8em,
            anchor=south west},
            ylabel=$y$,
            every axis y label/.style={at={(yticklabel cs:1,0)},
            xshift=2.7em,yshift=0.2em,
            anchor=south east},
            grid=both,
            grid style={draw=gray!25},
            xtick={-10, -8, ..., 10}, xtick style={yshift=-0.5ex},
            ytick={-10, -8, ..., 10}, ytick style={xshift=-0.5ex},
            yticklabel style={xshift=-0.5ex},
            minor tick num=1,
            minor tick length=0.5ex,
            minor x tick style={yshift=0.25ex}, minor y tick style={xshift=0.25ex},
        ]
        \end{axis}
    \end{tikzpicture}
\end{center}
\end{document}

[Tex/LaTex] TikZ: Drawing an arc from an intersection to an intersection

A solution which allows to draw intersection segments of any two intersections is available as tikz library fillbetween.

This library works as general purpose tikz library, but it is shipped with pgfplots and you need to load pgfplots in order to make it work:

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{fillbetween}

\begin{document}

\begin{tikzpicture}

\draw [name path=red,red] (120:1.06) circle (1.9);
%\draw [name path=yellow,yellow] (0:1.06) circle (2.12);
\draw [name path=green,green!50!black] (0:0.77) circle (2.41);
\draw [name path=blue,blue] (0:0) circle (1.06);

% substitute this temp path by `\path` to make it invisible:
\draw[name path=temp1, intersection segments={of=red and blue,sequence=L1}];
\draw[red,-stealth,ultra thick, intersection segments={of=temp1 and green,sequence=L3}];

\end{tikzpicture}

\end{document}

enter image description here

The key intersection segments is described in all detail in the pgfplots reference manual section "5.6.6 Intersection Segment Recombination"; the key idea in this case is to

create a temporary path temp1 which is the first intersection segment of red and blue, more precisely, it is the first intersection segment in the Left argument in red and blue : red. This path is drawn as thin black path. Substitute its \draw statement by \path to make it invisible.
Compute the desired intersection segment by intersecting temp1 and green and use the correct intersection segment. By trial and error I figured that it is the third segment of path temp1 which is written as L3 (L = left argument in temp1 and green and 3 means third segment of that path).

The argument involves some trial and error because fillbetween is unaware of the fact that end and startpoint are connected -- and we as end users do not see start and end point.

Note that you can connect these path segments with other paths. If such an intersection segment should be the continuation of another path, use -- as before the first argument in sequence. This allows to fill paths segments:

\documentclass{standalone}

\usepackage{tikz}
\usepackage{pgfplots}
\usetikzlibrary{fillbetween}

\begin{document}

\begin{tikzpicture}

\draw [name path=red,red] (120:1.06) circle (1.9);
%\draw [name path=yellow,yellow] (0:1.06) circle (2.12);
\draw [name path=green,green!50!black] (0:0.77) circle (2.41);
\draw [name path=blue,blue] (0:0) circle (1.06);

% substitute this temp path by `\path` to make it invisible:
\draw[name path=temp1, intersection segments={of=red and blue,sequence=L1}];
\draw[red,fill=blue,-stealth,ultra thick, intersection segments={of=temp1 and green,sequence=L3}]  
    [intersection segments={of=temp1 and green, sequence={--R2}}]
;

\end{tikzpicture}

\end{document}

You can use

 y filter/.expression={y==0 ? nan : y}

in the options of \addplot.
