title: How to count the particular values in the field in Google Data Studio
body: <p>I am trying to create a simple table in Google Data Studio, which fetches data from MySql table. For example, 
  "Peter
  John
  Mike
  Peter
  George
  Peter"</p>
  
  <p>The above are the set of values in a field,
  Here I have to count the number of "Peter" in the field and display the count. 
  Is it possible to display the count of particular values from a single field? If so, what function should I apply to get the required output?</p>
