是否可以在 Chart.js 折线图上制作虚线？并使图表全宽？请参阅随附的模型。

这是我当前的代码（只是简单的例子）：

    var ctx = document.getElementById("main-line-chart").getContext("2d");
    var line = ctx.setLineDash([5, 15]);

    var gradient = ctx.createLinearGradient(0, 0, 0, 300);
    gradient.addColorStop(0, 'rgba(40,175,250,.25)');
    gradient.addColorStop(1, 'rgba(40,175,250,0)');

    var data = {
        labels: ["January", "February", "March", "April", "May", "June", "July"],
        datasets: [
            {
                label: "My First dataset",
                pointDot : false,
                fillColor: gradient,
                strokeColor: "#28AFFA",
                pointColor: "#19283F",
                pointStrokeColor: "#28AFFA",
                pointHighlightFill: "#19283F",
                pointHighlightStroke: "#28AFFA",
                data: [65, 59, 80, 81, 56, null, null]
            },
            {
                label: "My Second dataset",
                fillColor: "rgba(0,0,0,0)",
                strokeColor: "rgba(255,255,255,.39)",
                pointColor: "#19283F",
                pointStrokeColor: "rgba(255,255,255,.39)", …
