title: Presenting multiple choice question results in Google Data Studio
body: <p>I want to use Google Data Studio to present the results of a form, in which I have a multiple choice question. Let's say we have option1, option2, and option3, and the respondents can choose any number of these: the result column will contain the responses separated by commas, e.g. "option1, option3".</p>
  
  <p>I would like to present that as a bar chart in Google Data Studio, but can't find how. </p>
  
  <p>If I set the field as "dimension", the chart has the correct labels for the bars, i.e. "option1", "option2" and "option3", but I can't find what to put as metrics to present in each one, how many times that has been responded.</p>
  
  <p>I've tried breaking them out as separate boolean columns, in which case I can compute the count of each answer, but don't know how to put them in the same bar chart...</p>
  
  <p>I expect to see a bar chart with labels "option1", "option2", "option3", and the count of each one as the height of each bar.</p>
