title: How to fix overlapping x axis in box plot (SAS)?
body: <p>I have been working with this annoying box plot for couple of DAYS!
  This is SAS University edition.
  Hope you could help me out unify same values in x axis. </p>
  
  <pre><code>proc import datafile="/folders/myfolders/sasuser.v94/chap1_3_97.xls"
                  out=work.q01_01
                  dbms=xls
                  replace;
  run;
  
  libname mylib '/folders/myfolders/sasuser.v94/mylib';
  data mylib.q01_01;
  set q01_01;
  run;
  
  proc print data = mylib.q01_01;
  run;
  
  /* print box plot */
  proc boxplot data=mylib.q01_01;
      plot smoking_rate * town_type ;
  run;
  </code></pre>
  
  <p>I expect only two values in x axis: city and country. However, the actual output is loops of city and country.</p>
