title: How can I change DataStudio default display in charts when I don't select anything in the drop-down control filter?
body: <p>I create drop-down list(Q1,Q2,Q3) to filter the charts and tables. If I don't select anything in the drop-down list, the charts and tables will automatically show everything(Q1,Q2,Q3) -- how can I change the default value charts and tables that are displaying to Q1's value only?</p>
  <p>To be more specific, if I don't select anything in the drop-down list, the charts and tables will show Q1's results; if I select Q2 in the drop-down list, the charts and tables will show Q2's result.
