Hello everyone:

I'm using the following code to plot a set of individual
rectangles, labeling each each rectangle with a number at
the center.  After that, the plots are combined in a single
one using Show. The problem is that only the label of the first
rectangle is shown in the combined plot. Could somebody point
out what is going and how to overcome the problem?

Regards,
Sergio
