var chartData = [
    { x: 1900, y: 4 }, { x: 1920, y: 3.0 },{ x: 1940, y: 3.8 },
    { x: 1960, y: 3.4 }, { x: 1980, y: 3.2 }, { x: 2000, y: 3.9 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Year',
        minimum: 1900, maximum: 2000, interval: 10,
        edgeLabelPlacement: 'Shift'

    primaryYAxis: {
        minimum: 2, maximum: 5, interval: 0.5,
        title: 'Sales Amount in Millions'
    },
    series:[{
        dataSource: chartData,
        xName: 'x', yName: 'y',
        opacity: 0.5, fill:'#69D2E7',
        name: 'Product A',border: { width: 2 },

Multicolored area

To render a multicolored area series, use the series type as MultiColoredArea, and inject the MultiColoredAreaSeries module using Chart.Inject(MultiColoredAreaSeries) method. The required segments of the series can be customized using the value, color, and dashArray.

index.js
index.html
var chart = new ej.charts.Chart({
   series:[{
        dataSource:  [{ 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: 25 }],
        xName: 'x', yName: 'y',
        type: 'MultiColoredArea',
        segmentAxis: 'X',
        segments: [{
                    value: 2007,
                    color: 'blue'
                }, {
                    value: 2009,
                    color: 'lightgreen'
                }, {
                    color: 'orange'
        }],
    }],
