domain option for pgfplot's \addplot ignored?

Question

I want to do a simple plot of goniometric functions with pgf in a beamer presentation:

\usepackage{tikz,pgfplots}
% ...
\begin{tikzpicture}
    \begin{axis}\addplot[domain=0:pi]{sin(deg(x))}; \end{axis}
\end{tikzpicture}

The domain options seems to be ignored, x axis spans from -6 to +6 regardless of what I specify. I tried to use /pgf/domain instead, with no change. What am I missing?

Answer 1

The code works, tested with pgfplots version 1.4.1.

On Ubuntu the current version from the repositories is 1.2.2, as the OP commented, which should be the cause. So an upgrade of pgfplots is recommended, which could be done manually from CTAN the most recent version is 1.5. However, when upgrading I recommend upgrading also the PGF package to the most recent version, for best compatibility.

Answer 2

Have you tried passing the domain option to tikzpicture instead of to the \addplot command? Works for me with 1.2.2.

\documentclass{article}

\usepackage{tikz}
\usepackage{pgf}
\usepackage{pgfplots}

\begin{document}

\begin{tikzpicture}[domain=0:50]
    \begin{axis}[ xlabel=$x$,
                  ylabel=$y$ ]
    \addplot[blue,dashed] {x^(2)};
    \addplot[green] {x^(3)};
    \end{axis}
\end{tikzpicture}

\end{document}
