  Antonio Leitao remind me that if, in my previous answer, I give some general
hints which allow also some sophisticated management, in the general and
standard cases, which are obviously the great majority, it is easier to use
the hooks given by PSTricks to format the labels.

  So, the next second example is simplest and more natural than the first one.

  P.S. * When some array manipulation macros are used inside a graphic (inside
a "pspicture" environment), as Antonio Leitao has done, we could have unwanted
moves. This was due to a spurious blank in the \get at max@count macro of
`arrayjob'. Investigating this point further, I found two other spurious
blanks in this file. I update it on
http://www.tug.org/applications/PSTricks/macros/arrayjob.sty

       * As Rolf Niepraschk tell me, it would really be better if this small
package can be officially diffused and put on CTAN. I just had asked to
Zhuhan Jiang the authorization to do it. These macros are completely unknown,
but as far as I know they are the most evoluted for this goal (for instance,
Stephan von Bechtolsheim give also such macros in one of his books, but they
are limited to mono-dimensional arrays). And these macros could also be used
to build some common data structures used in classical programming languages,
like linked lists and trees, allowing complex management of data.

\begin{pspicture}(-0.5,-0.5)(13,4)

  \multido{\iMonth=1+1}{12}{%
    \checkMonths(\iMonth)%
    \rput[B](\iMonth,-0.3){\tiny\cachedata}}
\end{pspicture}

\renewcommand{\pshlabel}[1]{{\checkMonths(#1)\tiny\cachedata}}
\begin{pspicture}(-0.5,-0.5)(13,4)
  \psaxes[showorigin=false]{->}(13,4)
\end{pspicture}
