在chart.js折线图中显示线条的特定颜色

Question

我有一个多线形图使用chart.js版本2.4和angular-chart.js。我想分别用红色和绿色显示这2条线，我不想在线下面填充颜色。我怎么才能做到这一点?

var app=angular.module("app", ["chart.js"]);
app.controller("LineCtrl", function ($scope) {
$scope.labels = ["January", "February", "March", "April", "May", "June", "July","August","September","October","November","December"];
$scope.series = ['one', 'two'];
$scope.data = [
[65, 59, 80, 81, 56, 55, 40, 30, 70, 30, 70, 30],
[28, 48, 40, 19, 86, 27, 90, 35, 70, 62, 75, 60]
]; 
$scope.onClick = function (points, evt) {
console.log(points, evt);
};
$scope.datasetOverride = [{ yAxisID: 'y-axis-1' }, { yAxisID: 'y-axis-2' }];
$scope.options = {
scales: {
  yAxes: [
    {
      id: 'y-axis-1',
      type: 'linear',
      display: true,
      position: 'left'
    },
    {
      id: 'y-axis-2',
      type: 'linear',
      display: true,
      position: 'right'
    }
  ]
  }
 };
});

像这样做，

ctrl.datasetOverride = [{
        fill: false,
        backgroundColor: [
            "#ED402A",
            "#36A2EB",
            "#FFCE56"
        ]
    }, {
        fill: false,
        backgroundColor: [
            "#F0AB05",
            "#36A2EB",
            "#FFCE56"
        ]
    }
];
