Range Area Chart in JavaScript Charts

Range Area

To render a range area series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

  • Set the series type: Define the series type as RangeArea in your chart configuration. This indicates that the data should be represented as a range area chart, which is ideal for visualizing a range of values for each data point. This type of chart is particularly useful for displaying data that has a range between a minimum and maximum value, such as temperature ranges, stock price ranges, or any other type of data that varies within a specific interval.

  • Inject the RangeAreaSeries module: Use the Chart.Inject(RangeAreaSeries) method to inject the RangeAreaSeries module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering range area series are available in your chart.

  • Provide high and low values: The RangeArea series requires two y-values for each data point, you need to specify both the high and low values. The high value represents the maximum range, while the low value represents the minimum range for each data point. These values define the upper and lower boundaries of the area for each point on the chart.

  • Provide high and low values: The RangeArea series requires two y-values for each data point, you need to specify both the high and low values. The high value represents the maximum range, while the low value represents the minimum range for each data point. These values define the upper and lower boundaries of the area for each point on the chart.

var chartData = [
    { x: 'Jan', high: 14, low: 4 },
    { x: 'Feb', high: 17, low: 7 },
    { x: 'Mar', high: 20, low: 10 },
    { x: 'Apr', high: 22, low: 12 },
    { x: 'May', high: 20, low: 10 },
    { x: 'Jun', high: 17, low: 7 },
    { x: 'Jul', high: 15, low: 5 },
    { x: 'Aug', high: 17, low: 7 },
    { x: 'Sep', high: 20, low: 10 },
    { x: 'Oct', high: 22, low: 12 },
    { x: 'Nov', high: 20, low: 10 },
    { x: 'Dec', high: 17, low: 7 }
];

var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Month',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 }
    },
    primaryYAxis:

            dataSource: chartData,
            xName: 'x',
            high: 'high',
            low: 'low'
        }
    ],

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName, high, and low properties.

var chartData = [
    { x: 'Jan', high: 14, low: 4 },
    { x: 'Feb', high: 17, low: 7 },
    { x: 'Mar', high: 20, low: 10 },
    { x: 'Apr', high: 22, low: 12 },
    { x: 'May', high: 20, low: 10 },
    { x: 'Jun', high: 17, low: 7 },
    { x: 'Jul', high: 15, low: 5 },
    { x: 'Aug', high: 17, low: 7 },
    { x: 'Sep', high: 20, low: 10 },
    { x: 'Oct', high: 22, low: 12 },
    { x: 'Nov', high: 20, low: 10 },
    { x: 'Dec', high: 17, low: 7 }
];

var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Month',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 }
    },
    primaryYAxis:
    {
        title: 'Temperature',
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0,
        maximum: 30,
        majorTickLines: { width: 0 }
    },
    series: [
        {
            type: 'RangeArea',
            dataSource: chartData,
            xName: 'x',
            high: 'high',
            low: 'low'
        }
    ],
    title: 'Monthly Temperature Range'
}, '#element');

The fill property can be used to apply a gradient color to the range area series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

var chartData = [
    { x: 'Jan', high: 14, low: 4 },
    { x: 'Feb', high: 17, low: 7 },

    { x: 'Oct', high: 22, low: 12 },
    { x: 'Nov', high: 20, low: 10 },
    { x: 'Dec', high: 17, low: 7 }

Empty points

Data points with null or undefined values are considered empty. Empty data points are ignored and not plotted on the chart.

Mode

Use the mode property to control handling of empty points. Available modes: Gap, Drop, Zero, Average. The default mode is Gap.

Events

Series render

The seriesRender event enables modification of series properties (for example, data, fill, or name) immediately before rendering. Use this event to adjust series appearance or to dynamically swap data sources.

var chartData = [
    { x: 'Jan', high: 14, low: 4 },
    { x: 'Feb', high: 17, low: 7 },
    { x: 'Mar', high: 20, low: 10 },
    { x: 'Apr', high: 22, low: 12 },
    { x: 'May', high: 20, low: 10 },
    { x: 'Jun', high: 17, low: 7 },
    { x: 'Jul', high: 15, low: 5 },
    { x: 'Aug', high: 17, low: 7 },
    { x: 'Sep', high: 20, low: 10 },
    { x: 'Oct', high: 22, low: 12 },
    { x: 'Nov', high: 20, low: 10 },
    { x: 'Dec', high: 17, low: 7 }
];

var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Month',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 }
    },
    primaryYAxis:
    {
        title: 'Temperature',
        labelFormat: '{value}˚C',
        lineStyle: { width: 0 },
        minimum: 0,

Point render

The pointRender event provides a hook to customize each data point (for example, marker shape, border, or fill) before it is drawn. Use this to apply per-point styling rules or conditional formatting.

var chartData = [
    { x: 'Jan', high: 14, low: 4 },
    { x: 'Feb', high: 17, low: 7 },
    { x: 'Mar', high: 20, low: 10 },
    { x: 'Apr', high: 22, low: 12 },
    { x: 'May', high: 20, low: 10 },
    { x: 'Jun', high: 17, low: 7 },
    { x: 'Jul', high: 15, low: 5 },
    { x: 'Aug', high: 17, low: 7 },
    { x: 'Sep', high: 20, low: 10 },
    { x: 'Oct', high: 22, low: 12 },
    { x: 'Nov', high: 20, low: 10 },
    { x: 'Dec', high: 17, low: 7 }
];

var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Month',
        edgeLabelPlacement: 'Shift',

        }
    ],
    title: 'Monthly Temperature Range',
    pointRender: function (args) {
