Graphics, Figures & Tables ⇒ tikz-3dplot | Margin around 3D Plot

[tomtom]

Hello.

I am using the tikz-3dplot package in order to plot some spherical harmonics.

The resulting tikzpicture contains an unsymmetric margin around the spherical harmonic. How can I get rid of this?

Code: Select all

\documentclass{article}

\pagestyle{empty}

\usepackage{tikz}
\usepackage{tikz-3dplot}


\newcommand{\sphPlot}[1]
{
\tdplotsetmaincoords{70}{135}
\begin{tikzpicture}[scale=1,tdplot_main_coords,line join=bevel,fill opacity=.7]
\tdplotsphericalsurfaceplot{48}{24}%[parametricfill]
{#1}
{black}
{red!60!black}%
{}%
{}%
{}%
;
\end{tikzpicture}
}

\begin{document}
%
\def\sphAA1M1 { \sphPlot{ 0.9*sin(\tdplottheta)*cos(-\tdplotphi)} } %2,-2
%
\fbox{
\sphAA1M1
}
%
\end{document}

Ok. I found a first hack:

Code: Select all

\usetikzlibrary{external}
\tikzexternalize
\tikzset{external/force remake}

and as option for the tikzpicture enviroment:

Code: Select all

trimm left, trimm right=0

Unfortunatly the result has some problem with determining its size.
