Tikz: define label font size under the node

Question

I create a picture of array which consists of nodes. I wonder how I can set the font size for the label which is below every cell (for example make it as scriptsize). This are my definitions:

\def\cells#1#2#3#4#5#6#7{
  \foreach [count=\i from 0] \j  in {1,...,#1} {
    \node[cell,label=below:\i] (cell\i) at (\i*0.5,0) {};
  }
}

\tikzset{
  cell/.style = {draw, minimum width=0.5cm, minimum height=0.5cm, minium size = 0.5cm}
}

Answer 1

Just add \scriptsize:

\node[cell,label=below:{\scriptsize \i}]

You can change the font or whatever in the same way.

Answer 2

I know it's more tedious for this simple example, but for educational purposes it might be interesting to see how to add proper TikZ styles to the label:

\node[cell,label={[font=\small, red, rotate=20]below:\i}]

Note that the braces around the value in label={[]stuff} are necessary.

Answer 3

A PSTricks solution:

\documentclass{article}

\usepackage{multido,pstricks}
\psset{dimen = m}

\begin{document}

\def\cells{11} % number of cells
\begin{pspicture}(\cells,1.4)
  \multido{\r = 0.5+1, \i = 0+1}{\cells}{%
    \psframe(!\r\space 0.5 sub 0.4)(!\r\space 0.5 add 1.4)
    \rput(\r,0.9){$0$}
    \rput(\r,0.1){\scriptsize $\i$}}
\end{pspicture}

\end{document}

Answer 4

Just 4 fun with PSTricks.

\documentclass[pstricks,border=12pt,12pt]{standalone}

\begin{document}
\begin{pspicture}[dimen=m](11,1.5)
    \foreach \i in {0,...,10}{\rput(\i,.5){\psframe(1,1)\rput(.5,.5){0}\uput[-90](.5,0){\i}}}
\end{pspicture}
\end{document}
