For ChartJS v2.x you can use update() to update the chart data without explicitly destroying and creating the canvas.

var chart_ctx = document.getElementById("chart").getContext("2d");

var chart = new Chart(chart_ctx, {
    type: "pie",
    data: {},
    options: {}
});

$.ajax({
    ...
}).done(function (response) {
    chart.data = response;
    chart.update();
});
