Maybe my translation is not good.
But what is the good word for a graphical representation of a string discrete uncontinius variable ?
A bar graph ?
Did PSPP do that ?

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
