Question

我很难搞清楚如何在我的Chart JS折线图中显示标签，图例和标题。我已直接从example复制代码（转载如下）。但是，标签＆＃34;我的第一个数据集＆＃34;没有出现在图表的任何地方，所以我无法分辨出哪一行。我也尝试过添加一个“标题”＆＃39;到我的数据集，但没有运气。任何人都知道我错过了什么？

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]
    }
]};

谢谢， Saswat
