is there a way I can add x and y axis titles on chart.js charts? I could not find a specific option for axis titles in the documentation...

Thanks in advance!

Original response

From the documentation:

var myLineChart = new Chart(ctx).Line(data, options);

var data = {
    labels: ["January", "February", "March", "April", "May", "June", "July"],
    datasets: [
        {
            label: "My First dataset",
            fillColor: "rgba(220,220,220,0.2)",
            strokeColor: "rgba(220,220,220,1)",
            pointColor: "rgba(220,220,220,1)",
            pointStrokeColor: "#fff",
            pointHighlightFill: "#fff",
            pointHighlightStroke: "rgba(220,220,220,1)",
            data: [65, 59, 80, 81, 56, 55, 40]
        },
        {
            label: "My Second dataset",
            fillColor: "rgba(151,187,205,0.2)",
            strokeColor: "rgba(151,187,205,1)",
            pointColor: "rgba(151,187,205,1)",
            pointStrokeColor: "#fff",
            pointHighlightFill: "#fff",
            pointHighlightStroke: "rgba(151,187,205,1)",
            data: [28, 48, 40, 19, 86, 27, 90]
        }
    ]
};

Where labels = x-axis labels

And for the Y-axis, with a little SO search:

var options = {   
    scaleLabel: function (valuePayload) {
        // Do something with valuePayload.value
        return valuePayload.value;
    }
};

var myLineChart = new Chart(ctx).Line(data, options);
