title: How to construct histograms with unequal class widths in SAS?
body: <p>I am trying to create histograms in sas with the help of proc univariate in sas. But it gives me histograms with equal class widths. Suppose i want to have a histogram with first class interval from 1  to 10 and second class interval from 10 to 100.
  I tried using-</p>
  
  <pre><code> proc univariate data=sasdata1.dataone;
   var sum;
   histogram sum/ midpoints=0 to 10 by 10 10 to 100 by 90 ;run;
  </code></pre>
  
  <p>But this does not work. What is the correct way of doing this?</p>
