title: How do I create new measure filtered by a dimension?
body: <p>Hello Currently I have a measure of Student count, I also have dimension of Student Year(Year 1, Year 2, Year 3, Year 4) and School(School 1, School 2, School 3). I am trying to visualize the percentage of Year 1 Student with respect to Student count in each school. That is why I am trying to make a new measure of student count filtered by Student Year(Year 1).</p>
  
  <p>So far I ended with percentage but with respect to total student count, not student count for each school. Tried a few stuff with calculated field, but I am not sure how I apply "Student count" only if "Student Year" = "Year 1"</p>
