# Artefacts in 3D-Plots when z-values exceed z-axis limits? [closed]

When plotting an expression using pgfplots, there are strange artefacts in places where the z-values are too big for the current axis. How do I fix it? Is there an equivalent to y domain for the z-axis?

\documentclass{article}

\usepackage{pgfplots}

\begin{document}
\begin{tikzpicture}
\begin{axis}[
xmin=-1.5,xmax=1.5,
ymin=-1.5,ymax=1.5,
zmin=0, zmax=1,
view={40}{20}]
surf,samples=40,opacity=0.3]
{1-x^2-y^2};
\end{axis}
\end{tikzpicture}
\end{document}

I can't reproduce this problem with Miktex 2.9 and using SumatraPDF or Adobe Acrobat X. Everything is clipped properly. –  percusse Jan 14 '12 at 15:17
If I use TexLive 2011 and the IDE Gummi then I get the same problem as Psirus. If I use TexLive 2011 and the IDE TexWorks then everything is clipped properly. –  DJP Jan 14 '12 at 15:28
Seems to be reader related. I was using evince, but it’s fine under Adobe Acrobat. Thank you guys. What’s the protocol here…close, delete, answer? –  Psirus Jan 14 '12 at 15:58
