Set data point label based on Value (Y) Series 1 and Value (Y) Series 2 data

I have two Y Series groupings, 'points completed' and 'points remaining' and am trying to set the label to be the Percent complete. 
 
Is it possible to dynamically set the series label (1) based on another series label (2)? 
 
So far, I have logic within the beforeDrawDataPointLabel(dph, label, icsc) function that stores the val in an object for YSeries1, then calls that for YSeries2. 
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
//Storing while iterating YSeries1
pointsCompletedList[dph.getBaseValue()] = dph.getDisplayValue();
</pre>
 
<pre class='_prettyXprint _lang-auto _linenums:0'>
//Fetching while iterating YSeries2
var pointsCompleted = pointsCompletedList[dph.getBaseValue()];
</pre>
 
After calculating I set the label: 
<pre class='_prettyXprint _lang-auto _linenums:0'>label.getCaption().setValue((percentComplete) + "%");</pre>
 
Where I'm stuck is when points remaining = 0. Then for that instance, it does not loop through YSeries2.

Is there another approach to this? Is it possible to set define one label per data point when you have two Y Series?

Can you attach some sample data, in a csv file and a report that uses that file, showing what all you're doing and what the issue is? I'll take a look at your current method and look if there's another way to get what you're wanting.

Wouldn't let me upload a .csv so I saved it as .txt. You should be able to update the file name extension to csv.
