title: Excel - Display certain information when interacting with a graph
body: <p>Is there a way to, if the user clicks on a graph or perhaps just hovers over it, it display selected data?</p>
  
  <p>Imagine a graph with 3 bars. The bars may, arbitrarily, represent the number of people who drive, walk, or use bikes. </p>
  
  <p>If I were to click on the bar representing those who ride bikes, is there a way to display the names of those people, for example (given that the names are associated with the data used to make the graph in rows elsewhere)?</p>
