How to do drilldown depending on which bar in the bar chart was being clicked?

[lctanlc]

I am running on Splunk 6.4.3 and below is my source that presents a bar chart with the name of the Action on x-axis and the count on y-axis:

testing

<panel>
  <chart>
    <search>
      <query> ...|stats count by Action </query>
    </search>
    <option name="charting.drilldown">all</option>
    ...
  </chart>
</panel>

Is it possible to bring up another bar chart when I clicked on one of the bar?
E.g.,
Bar chart shows the following, x-axis vs y-axis:
Action X = 250 count
Action Y = 50 count
Action Z = 2500 count

If I click on Action X, I would like to show another bar chart that shows a breakdown of Action X by department. I.e., query is ... Action = Action X | |stats count by Department.

you can use $click.value$ to set the new token based on what is clicked to open a new panel.

 <panel>
   <chart>
     <search>
       <query> ...|stats count by Action </query>
     </search>
     <drilldown>
         <set token="newpanel>$click.value|s$</set>
    </drilldown>
     <option name="charting.drilldown">all</option>
     ...
   </chart>
 </panel>
  .....
<query>...Action=$click.value|s$....
