Line

To render a line series, use series type as Line and inject LineSeries module using Chart.Inject(LineSeries) method.

var chartData = [
    { x: 2005, y: 28 }, { x: 2006, y: 25 },{ x: 2007, y: 26 }, { x: 2008, y: 27 },
    { x: 2009, y: 32 }, { x: 2010, y: 35 }, { x: 2011, y: 30 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Year',
        minimum: 2004, maximum: 2012, interval: 1
    },
    primaryYAxis: {
        minimum: 20, maximum: 40, interval: 5,
        title: 'Efficiency',
        labelFormat: '{value}%'
    },
    series:[{
        dataSource: chartData, width:2,
        xName: 'x', yName: 'y',
        name: 'India',
        //Series type as line
        type: 'Line'
    }],
    title: 'Efficiency of oil-fired power production'
}, '#element');

Multicolored line

To render a multicolored line series, use the series type as MultiColoredLine, and inject the MultiColoredLineSeries module using Chart.Inject(MultiColoredLineSeries) method. Here, the individual colors to the data can be mapped by using pointColorMapping.

var chartData = [
    { x: 2005, y: 28 }, { x: 2006, y: 25 },{ x: 2007, y: 26 }, { x: 2008, y: 27 },
    { x: 2009, y: 32 }, { x: 2010, y: 35 }, { x: 2011, y: 30 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Year',
        minimum: 2004, maximum: 2012, interval: 1
    },
    primaryYAxis: {
        minimum: 20, maximum: 40, interval: 5,
        title: 'Efficiency',
        labelFormat: '{value}%'
    },
    series:[{
        dataSource: chartData, width:2,
        xName: 'x', yName: 'y',
        name: 'India',
        //Series type as line
        type: 'Line'
    }],
    title: 'Efficiency of oil-fired power production'
}, '#element');

        fill: 'red',
        //line width as 4 for chart series
        width:4,
        //dash array value as 5,5
        dashArray: '5,5',
        xName: 'x', yName: 'y',
        name: 'India', type: 'Line'
