両方向を指す軸と軸ラベルの位置 (Tikz)。AD-AS 図

このようなグラフを再現したいのですが、図のような軸を作成する方法がわかりません。どなたか方法をご存知ですか? 軸が両方向を向いていない同様の例は次のとおりです。

:Tags: Coordinate systems


This example shows how the ``intersection of`` mechanism of Tikz work. Notice how a horizontal 
line is made from point B to allow the calculation to be done.

Caption: In a fixed exchange regime it might not be possible to reach internal balance 
(full employment and price stability) and external balance (some given level of net export) 
using only fiscal policy. At point B only point C and D can be reached via fiscal policy. 
Only by devaluing the country is able to reach the optimum level at point A.

編集: 現在のコードは次のとおりです:

\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}[
    scale=5,
    axis/.style={very thick, <->, >=stealth'},
    important line/.style={thick},
    every node/.style={color=black}
    ]
    % axis
    \draw[axis] (0.1,0)  -- (1.1,0) node(xline)[right] {$Y$};
    \draw[axis] (0,0.1) -- (0,1.1) node(yline)[above] {$\pi_s$};
    % Lines
    \draw[important line] (.15,.15) coordinate (A) -- (.85,.85)
        coordinate (B) node[right, text width=5em] {$AS$};
    \draw[important line] (.15,.85) coordinate (C) -- (.85,.15)
        coordinate (D) node[right, text width=5em] {$AD$};
\end{tikzpicture}
\end{document}

解決策: AD-AS 図に興味のある方のために、私がこれまでに達成できたのは以下のとおりです。かなり良い出来だと思います:

\documentclass{minimal}
\usepackage{tikz}
\usepackage{verbatim}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}[
    scale=5,
    axis/.style={very thick, <->, >=stealth'},
    important line/.style={thick},
    every node/.style={color=black}
    ]
    % axis
    \draw[axis] (0.1,0)  -- (1.1,0) node(xline)[midway,below] {$\hat{Y}$};
    \draw[axis] (0,0.1) -- (0,1.1) node(yline)[midway,left] {$  \hat{\pi}_s$};
    % Lines
    \draw[important line] (.15,.15) coordinate (A) -- (.85,.85)
        coordinate (B) node[right, text width=5em] {$AS$};
    \draw[important line] (.15,.85) coordinate (C) -- (.85,.15)
        coordinate (D) node[right, text width=5em] {$AD$};
    %shifted IS-LM diagram
    \draw[xshift=.2cm, red!52] (.15,.10) coordinate (A) -- (.85,.80)
    coordinate (B) node[right, text width=5em] {$AS'$};

    %arrows between intersections
    \draw[->, thick, black, >=stealth']
    (0.61,.59) -- (.72,.48)
    node[sloped, above, midway] {$\hat{\tau}^w_S$};
\end{tikzpicture}
\end{document}

答え1

両端に矢印の先端を付けるには、<->の代わりにを使用します->。

矢印の真ん中の上にラベルを書くには

\draw (0,0) -- (5,0) node[midway,above]{A};

midwayは の別名ですpos=0.5。
