Do you mean to draw ticks and labels at (0, $\pi$) and (0, $-\pi$)? You could do the following.I am trying to label the y axis with pi and -pi. How can I do that?
\def\npi{3.1416}
\begin{tikzpicture}
\draw[->] (0,0) -- (3.5,0) node[below] {$x$};
\draw[->] (0,-3.5) -- (0,3.5) node[left] {$y$};
\draw (2pt,\npi) -- (-2pt,\npi) node {$\pi$};
\draw (2pt,-\npi) -- (-2pt,-\npi) node {$-\pi$};
\end{tikzpicture}
Hi dwsmith,I am trying to label the y axis with pi and -pi. How can I do that?
Code:\begin{tikzpicture} \draw[->] (0,0) -- (3.5,0) coordinate (x axis); \draw[->] (0,-3.5) -- (0,3.5) coordinate (y axis); \end{tikzpicture}
\begin{tikzpicture} [COLOR=#0000ff]
%ticks[/COLOR]
[COLOR=#0000ff]\foreach \y/\ytext in {-3.14/-\pi,3.14/\pi}[/COLOR]
[COLOR=#0000ff]\draw (1pt,\y) -- (-3pt,\y) [/COLOR]
[COLOR=#0000ff]node[anchor=east] {$\ytext$}; [/COLOR]
[COLOR=#0000ff]%[/COLOR]
\draw[->] (0,0) -- (3.5,0) coordinate (x axis);
\draw[->] (0,-3.5) -- (0,3.5) coordinate (y axis);
\end{tikzpicture}
