  <p>Im new to SPSS so sorry if this is basic. Trying to product a graphical representation (line-graph) of the change in frequency for each option from a to b. And then a,b,c.</p>
  
  <p>I figure, for each variable I need to calculate the % for each option and then plot that.</p>
  
  <p>Any help would be greatly appreciated. </p>
