How to ungroup tooltips

[clu-7]

Overview

Describe the issue. What is the issue and what did you expect?

ChartsJS
Using vanilla ChartsJS, when you hover over different sections in the stacked bar chart, you can see the individual value.

Angular-ChartsJS
However, in when I use the angular-charts.js I get the stacked tooltip with 3 rows.

Is it possible to "unstack" the tooltip?

Solution: It seems like I found the area that I need to update. Looking at the angular-charts.js code, if I comment out:

  Chart.defaults.global.tooltips.mode = 'label';```

it works like it does originally in ChartsJS. So I need to figure out a way to override.

Hope this helps someone if they encounter the same issue!
