pgfplots
I am using cycle lists and the \addplot+ command to plot lines in different styles. I would like to plot several things using each style, however, like this:
% Plot using style 1
\addplot+ coordinates {...};
\addplot coordinates {...};
\addlegendentry{Style 1}
% Plot using style 2
\addplot+ coordinates {...};
\addplot coordinates {...};
\addlegendentry{Style 2}
How can I do this?
I wasn't sure if you wanted stacks or slabs, so here is both:

{ \draw[#3] (0,0) grid (\gridwidth,\gridheight);
\foreach \x [count=\c] in {#1}
{ \fill[#2] (\c-1,0) rectangle (\c,\x);
}
}
\newcommand{\drawslabs}[3]% dataarray, slaboptions, gridoptions
{ \draw[#3] (0,0) grid (\gridwidth,\gridheight);
\foreach \x in {1,...,\gridwidth}
{ \foreach \y in {1,...,\gridheight}
{ \pgfmathtruncatemacro{\colnum}{\x}
\pgfmathtruncatemacro{\rownum}{\gridheight+1-\y}
\getslab{\rownum}{\colnum}
\ifthenelse{\cachedata>0}
{\fill[#2] (\x-1,\y-1) rectangle (\x,\y);}
{}

By default, PGFPlots uses degrees for trigonometric functions, not radians. You can change this by setting trig format plots=rad:
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.12}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
trig format plots=rad,
axis equal,
hide axis
]
\addplot [domain=0:2*pi, samples=50, black] ({4*sin(x)}, {4*cos(x)});
\addplot [domain=0:2*pi,samples=200, red]({(4+sin(12*x))*sin(x)},{(4+sin(12*x))*cos(x)});
\end{axis}
\end{tikzpicture}
\end{document}

forget plotkey is the usual way to do this but\addlegendentry{}does not choose whichaddplotcommand it comes after. You have to draw the to-be-legended(!?) plots consecutively at the beginning. So you can collate the plots such that you draw them 1-2-3,1-2-3, in terms of style as follows
