title: Selecting a range of columns in a stacked chart and retrieving the related data
body: <p>I am trying to create a stacked chart where the columns represent time, where I can set a range and where I can retrieve data from the columns within that range.</p>
  <p><a href="https://i.stack.imgur.com/F3b4v.png" rel="nofollow noreferrer">This image is a good example of what the chart should look like.</a></p>
  <p>Using the example above I want to be able to set a range between March and July and be able to retrieve the data from the columns within that range. The range would in practice be an x axis version of the Reference Zone.</p>
  <p>Is something along these lines possible and if so what would the required events be? The current method I am considering attempting is using the chartClick event to try and set a range.</p>
  <p>Related to this question is dragging and dropping a element outside the chart possible? The examples I've seen have been restricted to the chart itself</p>
