Hi

A possible solution to your question 2:

1. Compute the number of persons (say variable is nb) who replied 1,2,3,4 or
5 to each question using aggregate
2. just before printing the graphs:
IF nb=0 nb=.0001.

This small amount will force the program to show all questions even if
nobody selected that answer, the .0001 will look like a zero on the chart.
