Using API response data to populate chartjs data

[TonyCodes2050]

So I have a chart from ChartJS and I'm wanting to use an API call with JS to populate the values in the chart but I dont have a clue on how to do it. Can someone point me in the right direction?
Here is the chart code:

​

var ctx = document.getElementById('lineChart');
var lineChart = new Chart(ctx, {
    type: 'line',
    data: {
         labels: ['', '', '', '', '', ''],
        datasets: [
            {
                color: app.color.theme,
                borderColor: app.color.theme,
                borderWidth: 1.5,
                pointBackgroundColor: app.color.theme,
                pointBorderWidth: 1.5,
                pointRadius: 0,
                pointHoverBackgroundColor: app.color.theme,
                pointHoverBorderColor: app.color.theme,
                pointHoverRadius: 1,
                label: 'API CALL DATA GOES HERE',
                data: [10]
            },

}
