[Tex/LaTex] Making mesh grid lines transparent in surface plot with pgfplots

Question

I need to make a partly transparent, one color, surface plot. Additionally I want to control the transparency of mesh lines. Running this code:

\documentclass{standalone}
\usepackage{tikz,pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[]
\addplot3[surf, color=blue, opacity=0.5, domain=-2:2, faceted color=blue] {exp(-x^2-y^2)};
\end{axis}
\end{tikzpicture}
\end{document}

Produces the desired result only for the faces. Does pgfplots provide an option to control the transparency of mesh lines too?

Answer 1

The opacity parameter controls transparency of mesh lines and surfaces. To make mesh lines much more transparent you can add fill opacity and decrease opacity:

\documentclass{standalone}
\usepackage{tikz,pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[]
\addplot3[surf, color=blue, opacity=0.01,fill opacity=0.5, domain=-2:2, faceted color=blue] {exp(-x^2-y^2)};
\end{axis}
\end{tikzpicture}
\end{document}
