Chart.js: [BUG] labelColor when rendering an array of labels is not working

[brenolf]

Expected Behavior

When returning an array of objects from labelColor on tooltips.callbacks, the squares should get the colour returned from the function.

Current Behavior

When returning an array from labelColor on tooltips callbacks, all squares appear black.

Possible Solution

N/A

Steps to Reproduce (for bugs)

Context

I was trying to add thousand separators, and for that I needed to edit the label callback on tooltips. I then realized I would also need to override labelColor in order to get the previous behaviour, but it didn't work as expected.

Environment

• Chart.js version: 2.5.0
• Browser name and version: Google Chrome Version 56.0.2924.87 (64-bit)

@brenolf the labelColor tooltip is called for each item in the tooltip already, so no need to return an array. See http://jsbin.com/rezecuzeju/1/edit?html,js,output

This is still an issue, I believe. If you return an array in the label callback, it makes multiple labels, but there is no way to define multiple colors. They all have to be the same color.

I'm also experiencing this same issue, all label colours are the same even though I am specifying an array of different colours.

Not sure if you guys are still looking for it but here what worked on my end

            ```

tooltips: {
mode: 'index',
intersect: false,
callbacks: {
label: function(tooltipItem, data) {
var val = (data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index] != '') ? data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index] : 'N/A';
var ctg = data.datasets[tooltipItem.datasetIndex]['label']
return ctg + ' : ' + val;
},
}
},
```

but with this, you'll only get what is the current Category color
