title: Get underlying data in R(ggplotly2)
body: <p>I have developed some graphs in R using ggploty2 package. 
  there are methods to show data on mouse hover. I wonder if there is any way to get the underlying data on this event. </p>
  
  <p>Ex: I have a bar chart with sum of sales in each months of all products.</p>
  
  <p>if i mouse hove i can see the number of sales of that month, but i want all the sales details of that in a different place/div. </p>
  
  <p>is it possible to it in D3.js/R or any visualization tool. </p>
  
  <p>Thanks in advance  </p>
