我想使用 TikZ 绘制下图(旋转 180 度——我不知道为什么它会颠倒过来):
这似乎应该很容易,我尝试使用 ARC 函数,但一无所获。有人对此有什么想法吗?
这是我尝试过的:
\def\R{\mathbb{R}}
\newcommand{\cvx}{convex}

\begin{figure}
\begin{tikzpicture}[scale=0.5]
\scriptsize
\draw (0,11.5) -- (0,0) node[below left]{$0$} -- (11,0) node[below right]{$Z$};
\node [above left] at (0,11){$\chi$};
\node [above] at (0,12){$$Consumption$$};
\node [below] at (5.5,0){$\Delta$ in $Z$};
\draw (0,0)arc(90:-90:11cm and 5.5cm);
\draw (0,5.5) node[below left]{$t^*$} -- (11,5.5);
\draw (11.2,11) -- (11.7,11) -- (11.7,5.5) -- (11.2,5.5);
\node[align=left, right] at (11.7,8.25) {Prohibitive\\Range};
\draw[fill=gray] (11,5.5)arc(0:90:11cm and 5.5cm);
\draw[fill=gray] (11,5.5) -- (0,5.5) -- (0,11);
