# Symmetric Economic Curves

When I try to create symmetric curves for the left of the y-axis I get weird results. Does anyone have any idea what to do to get symmetric results?

\begin{tikzpicture}[scale=0.5]
\draw[thick] (0,11) node[left]{$P$}--(0,0)--(12,0) node[below]{$Y$};
\draw[thick] (0,-11) node[left]{$L$}--(0,0)--(12,0);
\draw[thick] (-11,0) node[left]{$W/P$}--(0,0)--(12,0);

\draw (1,8) to [out=280,in=175] (8,1);
\node [right] at (8,1) {$AD(M_0)$};
\draw (3,8) to [out=280,in=175] (8,3);
\node [right] at (8,3) {$AD(M_1)$};
\draw(5,0)--(5,9)node[right]{$AS$};

\node[left] at (0,4.2){$P_1$};
\draw[dotted](0,4.2)--(5,4.2);

\node[left] at (0,1.9){$P_1$};
\draw[dotted](0,1.9)--(5,1.9);

\draw (-1,8) to [out=-0] (-8,1);
\node [left] at (-8,1) {$W_0$};
\draw (-3,8) to [out=0,in=175] (-8,3);
\node [right] at (-8,3) {$W_1)$};
\draw(5,0)--(5,9)node[right]{$AS$};

\foreach \Point/\PointLabel in {(5,6)/A, (6,5)/B}
\draw[fill=black] \Point circle (0.05) node[above] {$\PointLabel$};
\end{tikzpicture}

• welcome -- please see the answer below -- in addition you may like to correct the label A and B by editing the syntax -- \draw[fill=black] \Point circle (0.05) node[right] {$\PointLabel$}; – js bibra Oct 24 at 15:07

If you want to mirror something, you can also invoke the magic mirr— ...ehm, I mean a scope and apply in your case xscale=-1.

Then you don't need to calculate anything. Of course whether this approach is convenient or not depends on your case, but for your question is a possible solution.

By the way, I have fixed some of your commands that were redundant, for example you can attach a node to a \draw without having to explicitly write it as a separate one.

Is it better now -- i have also corrected the label W1 -- it was misaligned \begin{tikzpicture}[scale=0.5]
\draw[thick] (0,11) node[left]{$P$}--(0,0)--(12,0) node[below]{$Y$};
\draw[thick] (0,-11) node[left]{$L$}--(0,0)--(12,0);
\draw[thick] (-11,0) node[left]{$W/P$}--(0,0)--(12,0);

\draw (1,8) to [out=280,in=175] (8,1);
\node [right] at (8,1) {$AD(M_0)$};
\draw (3,8) to [out=280,in=175] (8,3);
\node [right] at (8,3) {$AD(M_1)$};
\draw(5,0)--(5,9)node[right]{$AS$};

\node[left] at (0,4.2){$P_1$};
\draw[dotted](0,4.2)--(5,4.2);

\node[left] at (0,1.9){$P_1$};
\draw[dotted](0,1.9)--(5,1.9);

\draw (-1,8) to [out=260,in=15] (-8,1);
\node [left] at (-8,1) {$W_0$};
\draw (-3,8) to  [out=260,in=15](-8,3);
