I have a multi line chart using chart.js version 2.4 and angular-chart.js.I want to display the 2 lines in red and green respectively and I donot want to fill color beneath lines .How can i achieve this?

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'
}
]
}
};
});

Answer

Do something like this,

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

];
