Stacked bar

To render a stacked bar 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 StackingBar in your chart configuration. This indicates that the data should be represented as a stacked bar chart, where each bar consists of multiple segments stacked horizontally on top of each other.

index.js
index.html
var stackedData = [
    { x: 'Jan', y: 6, y1: 6, y2: -1 },   { x: 'Feb', y: 8, y1: 8, y2: -1.5 },
    { x: 'Mar', y: 12, y1: 11, y2: -2 }, { x: 'Apr', y: 15, y1: 16, y2: -2.5 },
    { x: 'May', y: 20, y1: 21, y2: -3 }, { x: 'Jun', y: 24, y1: 25, y2: -3.5 },
    { x: 'Jul', y: 28, y1: 27, y2: -4 }, { x: 'Aug', y: 32, y1: 31, y2: -4.5 },
    { x: 'Sep', y: 33, y1: 34, y2: -5 }, { x: 'Oct', y: 35, y1: 34, y2: -5.5 },
    { x: 'Nov', y: 40, y1: 41, y2: -6 }, { x: 'Dec', y: 42, y1: 42, y2: -6.5 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Months'
    },
    primaryYAxis:
    {
        title: 'Percentage (%)',
        minimum: -20,
        maximum: 100,
        labelFormat: '{value}%',
        edgeLabelPlacement: 'Shift'
    },
    series: [
        {
            //Series type as stacked bar
            type: 'StackingBar', name: 'Apple',
            dataSource: stackedData, xName: 'x', yName: 'y'
        }, {
            type: 'StackingBar', name: 'Orange',
            dataSource: stackedData, xName: 'x', yName: 'y1'
        }, {
            type: 'StackingBar', name: 'Wastage',
            dataSource: stackedData, xName: 'x', yName: 'y2'
        }
    ],
    title: 'Sales Comparison'
}, '#element');

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 and yName properties.

index.js
index.html
var stackedData = [
    { x: 'Jan', y: 6, y1: 6, y2: -1 },   { x: 'Feb', y: 8, y1: 8, y2: -1.5 },
    { x: 'Mar', y: 12, y1: 11, y2: -2 }, { x: 'Apr', y: 15, y1: 16, y2: -2.5 },
    { x: 'May', y: 20, y1: 21, y2: -3 }, { x: 'Jun', y: 24, y1: 25, y2: -3.5 },
    { x: 'Jul', y: 28, y1: 27, y2: -4 }, { x: 'Aug', y: 32, y1: 31, y2: -4.5 },
    { x: 'Sep', y: 33, y1: 34, y2: -5 }, { x: 'Oct', y: 35, y1: 34, y2: -5.5 },
    { x: 'Nov', y: 40, y1: 41, y2: -6 }, { x: 'Dec', y: 42, y1: 42, y2: -6.5 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        valueType: 'Category',
        title: 'Months'
    },
    primaryYAxis:
    {
        title: 'Percentage (%)',
        minimum: -20,
        maximum: 100,
        labelFormat: '{value}%',
        edgeLabelPlacement: 'Shift'
    },
    series: [
        {
            //Series type as stacked bar
            type: 'StackingBar', name: 'Apple',
            dataSource: stackedData, xName: 'x', yName: 'y'
        }, {
            type: 'StackingBar', name: 'Orange',
            dataSource: stackedData, xName: 'x', yName: 'y1'
        }, {

Series customization

The following properties can be used to customize the stacked bar series.

Fill

The fill property determines the color applied to the series.

var chartData = [
  { x: 'Jan', y: 6, y1: 6, y2: -1 },
  { x: 'Feb', y: 8, y1: 8, y2: -1.5 },

The fill property can be used to apply a gradient color to the stacked bar 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.

  { x: 'Jan', y: 6, y1: 6, y2: -1 },
  { x: 'Feb', y: 8, y1: 8, y2: -1.5 },

Opacity

The opacity property specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

Stacking group

Use the stackingGroup property to group stacked bars and 100% stacked bars. Bars with the same group name are stacked on top of each other.

Cylindrical stacked bar chart

To render a cylindrical stacked bar chart, set the columnFacet property to Cylinder in the chart series. This property transforms the regular stacked bars into cylindrical shapes, enhancing the visual representation of the data.
