Answer 1

Add a legend to your config:

{

    type: 'pie',
    data: {
        ...
    },
    options: {
        legend: {
            position: 'top'
        }
    }
    ...
}

Example :

 var ctx = document.getElementById("myChart").getContext('2d'); var myChart = new Chart(ctx, { type: 'pie', data: { labels: [ "My", "Dataset", "Labels" ], datasets: [{ data: [ 22, 33, 44 ], backgroundColor: [ '#007bff', '#dc3545', '#9932CC' ] }] }, options: { legend: { position: 'top' } } });
