Format Chart.JS Data Element To Be Currency

Question

I found that you can format the x or y axis of Chart.JS to currency by a quick JavaScript callback function

callback: function(value, index, values) {
    if (parseInt(value) >= 1000) {
        return '$' + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
    } else {
        return '$' + value;
    }
}
}

but this does not seem to be the case for the data: In my instance this is a JavaScript 1D Array that holds numeric values, and I want to add a dollar sign, and comma where applicable. How can this be added with Charts.jS

EDIT
This is how I am populating my JSON array - and I want to format the data in the data: values

var barChartData = {
    labels: labelsarr,
    datasets: [{
        label: 'Amount',
        backgroundColor: 'rgba(200, 200, 200, 0.75)',
        borderColor: 'rgb(255, 99, 132)',
        borderWidth: 1,
        data: values
    }]

};

And the JSON array is in this format ["AAAA",100,10000,2310,24420,30,50000,400000,70000,700,823200,923200,1111]

I want to format starting at index[1] to show $ and currency. How can this be achieved?

2nd Edit Time
I try to add title and format both data points and left axis as currency with below syntax, but this no longer displays anything on my page.

var ctx = document.getElementById('canvas').getContext('2d');
var chart = new Chart(ctx, {
    type: 'bar',
    data: {
        labels: labelsarr,
        datasets: [{
            label: 'Test',
            data: values,
            backgroundColor: 'rgba(0, 119, 204, 0.8)',
        }]
    },
    options: {
        responsive: true,
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero: true,
                    callback: function(value, index, values) {
                        if (parseInt(value) >= 1000) {
                            return '$' + value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
                        } else {
                            return '$' + value;
                        }
                    }
                }
            }]
        },
        legend: {
            position: 'top',
        },
        title: {
            display: true,
            text: '<?php echo $name ?> Test'
        }
        tooltips: {
            callbacks: {
                label: function(t, d) {
                    var xLabel = d.datasets[t.datasetIndex].label;
                    var yLabel = t.yLabel >= 1000 ?
                        '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") :
                        '$' + t.yLabel;
                    return xLabel + ': ' + yLabel;
                }
            }
        }
    }
});

Answer 1

This can be achieved using the following tool-tips label callback function ...

tooltips: {
   callbacks: {
      label: function(t, d) {
         var xLabel = d.datasets[t.datasetIndex].label;
         var yLabel = t.yLabel >= 1000 ? '$' + t.yLabel.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",") : '$' + t.yLabel;
         return xLabel + ': ' + yLabel;
      }
   }
}
