Custom Data Labels on stacked barchart

[sll1966]

How do i add labels to the stacked barcode series?
For instance, sometimes you want the value being graphed, and in my case i need to also include some other text.
Below shows how a non stacked can use animationComplete callback

Results from database
Machine StdHoursForWOs

A1452	<WO>54182526|59.62</WO><WO>54181152|16.68</WO>
A1460	<WO>54177330|5.50</WO>
A1476	<WO>54195375|3.46</WO><WO>54177222|0.20</WO><WO>54195386|12.08</WO>

For the Horizontal stacked barchart, i want the first bar to have label of A1452, and series of 59.62, 16.68, with data labels to include the WO and amount.

I know i will have to peel apart the results from the API to split the data amount into the series, and i figure in the same loop i could set the data labels. Something like below

let serie = '';
let myArray = [];
result.forEach(function(row){
	labels.push(Object.values(Object.values(row))[0]);
	Object.forEach(function(cell)){
	serie = Object.values(Object.values(row))[cell].replace("<WO>","").replace("</WO>","");  // Remove tags
	myArray = (Object.values(Object.values(row))[cell].split("|");  // split data value
		series.push(myArray[1]);,
		serieslabel.push(myArray[0]+myArray[1]);  // This is what i don't know how to do
	});
});
const chartdata = { labels: labels,  series: series };
