I'm using the following code to draw the electron wavefunction around an atom. I'd like to fade out the line towards it's end. I've read all the relevant questions I can find, but I fail to get what I want.

Do you have any ideas?

\documentclass[]{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[scale=3,very thick]
\draw[color=red,domain=0:12.56,samples=200,smooth] plot (canvas polar cs:angle=\x r,radius={28-8*sin(2.25*\x r)});

\draw[dashed,domain=0:6.28,samples=200,smooth] plot (canvas polar
cs:angle=\x r,radius={0.5 r});
\draw[fill=black](0,0)circle (.5mm);
\end{tikzpicture}
\end{document}

Where is the end of the line in the output? Isn't it a closed shape line? – enthu Jan 26 '15 at 20:03
Not a closed shape, a polar plot between an angle of 0 and 4Pi. – JPing Jan 26 '15 at 20:19
You don't actually use any of the pgfplots functionality here, as far as I know (i.e. you have no \addplot and no \begin{axis}... Any reason to load pgfplots then? – darthbith Jan 26 '15 at 20:47
Probably not now you mention it! – JPing Jan 26 '15 at 21:03

Have you read this: http://tex.stackexchange.com/questions/141378/path-following-color-gradient-in-tikz – Herr K. Jan 27 '15 at 02:45
Is there any way of getting this questions "bumped" so someone who can answer it might see it? – thosphor Nov 08 '16 at 15:06
