I don't understand how a "histogram for a string variable" has any meaning.

A histogram groups numbers into ranges - you can't "group strings into ranges",
because a string does not contain quantative information.

Slightly more formally, a histogram is an approximation to a probability 
distribution.  Probability distributions only has a meaning for continuous 
variables.  Strings are not continuous variables.

Perhaps you have misunderstood your class requirements (or perhaps the lecturer
is asking you a trick question to make sure you are alert!)

     Hi everyone,
     I trying PSPP for the first the, in place of SPSS.
     I'm a student, and I can afford to go to the school lab everyday
     for SPSS work.
     So, I,m tryting PSPP 0.7.9 included with Ubuntu 13.10
     I trying to do histogram of the gender distribution on a pretty
     small echantillon.
     I read on a lot of forum that PSPP doesn't output histogram for
     string variable.
     Unfortunatly is a requirement for the class.
     I would like to see if it's possible to save the PSPP file in
     LibreOffice Calc to do it.
     Actually, I use R to do the job.
     Thank you
