How to create a drilldown pass the data in the legend of a timechart?

[KindaWorking]

I am relatively new to all things splunk.
I am trying to set up a timechart that will pass a value onto another input. I can pass through $click.value$ fine along with $click.value2$. However in a time chart, that passes either the date or the count. I want it to send through the data sitting in the legend.

<drilldown>
  <set token="form.Address1">$click.value$</set>
  <set token="Address1">$click.value$</set>
</drilldown>

What can I use instead of $click.value$?

EDIT: More clarification. I am tracking the use of IP addresses. I have a search (see below) that will timechart which IP address performed a particular search over time.

   ...|timechart count by IPAddress

I then would like to pass through via drilldown which IP address I clicked on.
$click.value$ passes through the date(x axis). $click.value2$ passes through the count (y axis). How do I pass through the IP address instead?

Pretty much, when you click on a colored line in the timechart, I want to pass through (via drilldown) the data in the legend (in this case the IP address).

$click.name2$ is what I needed.

$click.name$ passes through _time where $click.name2$ passes through the data sitting on the legend for what you clicked on (however it does NOT work when you actually click on the legend).

Need more clarification... your query, sample output and what you want pass would help us to provide the answer correctly.
