You can do this using a function instead of a template string. As you guessed you need to figure out the name from the number.

Here is a generic sample

var numberNames = [
    { number: 1, name: "Eating" },
    { number: 2, name: "Drinking" },
    { number: 3, name: "Sleeping" },
    { number: 4, name: "Designing" },
    { number: 8, name: "Coding" },
    { number: 9, name: "Cycling" },
    { number: 10, name: "Running" }
];


var data = {
    labels: numberNames.map(function(e) { return e.number }),
    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, 9, 10, 56, 55, 40]
        }
    ]
};

var ctx = document.getElementById("myChart").getContext("2d");
var myChart = new Chart(ctx).Radar(data, {
    tooltipTemplate: function (valueObject) {
        return numberNames.filter(function (e) { return e.number === valueObject.label })[0].name + ': ' + valueObject.value;
    }
});

I used numberNames but you should be able to replace that with tempComp (after adjusting the labels property and the tooltipTemplate function body slightly).
