# how do I escape a comma?

I have a tikz picture and at some point I draw the following node:

\node[thick,
scale=0.5,
minimum size=1.3cm,
fill=red,
circle,
draw,
fill opacity=0.3,
label=right:$= (0 1 0 1 0 \ldots)$
] (the) at (6.2, 1.5) { };


The thing is that I want to separate the 0 1 0 1, etc with commas. I can't do that, because I think TikZ thinks it separates the next parameter in the square brackets. How can I escape the comma?

Put braces around the label. – clemens Oct 30 '12 at 22:25
thanks, that works. – kloop Oct 30 '12 at 22:26

By eating healthy or using braces around shady characters.

\begin{tikzpicture}
\node[thick,
scale=0.5,
minimum size=1.3cm,
fill=red,
circle,
draw,
fill opacity=0.3,
label=right:{$= (0,1,0,1,0,\ldots)$}
] (the) at (6.2, 1.5) { };
\end{tikzpicture}
