The following are my code. I used the axis environment for better axis style. I try to add nodes at g^W=g^L, which is a point on the y-axis, but the axis environment seemes to cut off anything outside the axis. What should I do?


\begin{tikzpicture}[scale = 1.2]
        axis lines = left, axis line style = thick,  unit vector ratio=1 1 1, xtick={0,8},
        xticklabels = {$p^w=0$, $p^w=1$},
        yticklabels = {$g^L-\beta$,$g^W=g^L$,$g^w+\alpha$}]
        \addplot[mark=none, dashed] coordinates {(8, 0) (8, 7)}; 
        \addplot[domain=0:8, dashed] {1.5};
        \addplot[domain=0:8, dashed] {3};

        \node[black,right] at (axis cs:8,1.5){\small{$W=0$}};
        \node at (axis cs:8,1.5) [circle, scale=0.3, draw=black!80,fill=black!80] {};
        \node at (axis cs:8,3) [circle, scale=0.3, draw=black!80,fill=black!80] {};
        \node at (0,3.5) [circle, scale=0.3, draw=black!80,fill=black!80] {};
\caption{A caption.}

If you add

clip mode=individual 

to the axis options, the diagrams (with addplot) will be clipped, but the nodes will not.

Otherwise, clip = false will avoid any clipping.

PS: you need a \pgfplotsset{compat=1.9} or whatever added, to avoid surprises...

  • It worked! Thanks. Just a question, what does clip mean? – Kun Apr 2 '16 at 14:18

    clip means to cut off all that will go outside the axis range. Imagine a function like 1/x which will go unbounded otherwise... – Rmano Apr 2 '16 at 14:23
