指向兩個方向的軸和定位軸標籤 (Tikz)。 AD-AS圖

我想重現這樣的圖表，但我不知道如何製作如圖所示的軸。有人知道怎麼做嗎？沒有軸指向兩個方向的類似範例是：

:Title: Intersection of
: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.

\begin{tikzpicture}[
    scale=5,
    axis/.style={very thick, ->, >=stealth'},
    important line/.style={thick},
    dashed line/.style={dashed, thin},
    pile/.style={thick, ->, >=stealth', shorten <=2pt, shorten

       second line={(C) -- (D)}) coordinate (E) circle (.4pt)

    % The E point is placed more or less randomly

    % Line connecting out and ext balances
    \draw [pile] (out) -- (intersection of A--B and out--[shift={(0:1pt)}]out)
        coordinate (extbal);
    \fill[red] (extbal) circle (.4pt) node[above] {$C$};
    % line connecting  out and int balances
    \draw [pile] (out) -- (intersection of C--D and out--[shift={(0:1pt)}]out)
        coordinate (intbal);
    \fill[red] (intbal) circle (.4pt) node[above] {$D$};
    % line between out og all balanced out :)
    \draw[pile] (out) -- (E);
\end{tikzpicture}
\end{document}

編輯：我目前的程式碼是：

\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}

乾杯，

解決方案：對於那些對 AD-AS 圖感興趣的人，這就是我迄今為止所實現的目標。我認為這是相當不錯的：

\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}

要兩端都有箭頭，請使用<->代替->。

若要在箭頭中間上方寫入標籤，請使用

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

midway是 的別名pos=0.5。
