100% Stacked Bar

To render a 100% 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 StackingBar100 in your chart configuration. This indicates that the data should be represented as a 100% stacked bar chart, with segments that show the percentage contribution of each part.
var stackedData = [
    { x: 2000, y: 0.61, y1: 0.03, y2: 0.48},
    { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
    { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
    { x: 2003, y: 1,    y1: 0.09, y2: 0.61 }, 
    { x: 2004, y: 1.19, y1: 0.14, y2: 0.63 },
    { x: 2005, y: 1.47, y1: 0.20, y2: 0.64 },
    { x: 2006, y: 1.74, y1: 0.29, y2: 0.66 }, 
    { x: 2007, y: 1.98, y1: 0.46, y2: 0.76 },
    { x: 2008, y: 1.99, y1: 0.64, y2: 0.77 },
    { x: 2009, y: 1.70, y1: 0.75, y2: 0.55 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Months'
    },
    primaryYAxis:
    {
        title: 'Percentage (%)',
        labelFormat: '{value}%'
    },
    series: [
        {
            //Series type as 100% stacked bar
            type: 'StackingBar100',
            dataSource: stackedData, 
            xName: 'x', 
            yName: 'y',
            name: 'Apple'
        }, 
        {
            type: 'StackingBar100',
            dataSource: stackedData, 
            xName: 'x', 
            yName: 'y1',
            name: 'Orange'
        }, 
        {
            type: 'StackingBar100',
            dataSource: stackedData, 
            xName: 'x', 
            yName: 'y2',
            name: 'Wastage'
        }
    ],
    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.

var stackedData = [
    { x: 2000, y: 0.61, y1: 0.03, y2: 0.48},
    { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
    { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
    { x: 2003, y: 1,    y1: 0.09, y2: 0.61 }, 
    { x: 2004, y: 1.19, y1: 0.14, y2: 0.63 },
    { x: 2005, y: 1.47, y1: 0.20, y2: 0.64 },
    { x: 2006, y: 1.74, y1: 0.29, y2: 0.66 }, 
    { x: 2007, y: 1.98, y1: 0.46, y2: 0.76 },
    { x: 2008, y: 1.99, y1: 0.64, y2: 0.77 },
    { x: 2009, y: 1.70, y1: 0.75, y2: 0.55 }
];
var chart = new ej.charts.Chart({
    primaryXAxis: {
        title: 'Months'
    },
    primaryYAxis:
    {
        title: 'Percentage (%)',
        labelFormat: '{value}%'
    },
    series: [
        {
            //Series type as 100% stacked bar
            type: 'StackingBar100',
            dataSource: stackedData, 
            xName: 'x', 
            yName: 'y',
            name: 'Apple'
        }, 
        {

Series customization

The following properties can be used to customize the 100% stacked bar series.

Fill

The fill property determines the color applied to the series.

var stackedData = [
  { x: 2000, y: 0.61, y1: 0.03, y2: 0.48 },
  { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
  { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
  { x: 2003, y: 1,    y1: 0.09, y2: 0.61 },

        yName: 'y',
        name: 'Apple',
        fill: '#483D8B'

The fill property can be used to apply a gradient color to the 100% 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.

var stackedData = [
  { x: 2000, y: 0.61, y1: 0.03, y2: 0.48 },
  { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
  { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
  { x: 2003, y: 1, y1: 0.09, y2: 0.61 },
  { x: 2004, y: 1.19, y1: 0.14, y2: 0.63 },
  { x: 2005, y: 1.47, y1: 0.20, y2: 0.64 },
  { x: 2006, y: 1.74, y1: 0.29, y2: 0.66 },
  { x: 2007, y: 1.98, y1: 0.46, y2: 0.76 },
  { x: 2008, y: 1.99, y1: 0.64, y2: 0.77 },
  { x: 2009, y: 1.70, y1: 0.75, y2: 0.55 }
];

Opacity

The opacity property controls the transparency of the fill and affects how the series blends with background or overlapping series.

var stackedData = [
  { x: 2000, y: 0.61, y1: 0.03, y2: 0.48 },
  { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },

Use the border property to configure the border width, color, and dasharray of the 100% stacked bar series.

100% Cylindrical stacked bar chart

To render a 100% cylindrical stacked bar chart, set the columnFacet property to Cylinder in the chart series. This property transforms the regular 100% stacked bars into cylindrical shapes, enhancing the visual representation of the data.

var cylindricalData = [
    { x: 2000, y: 0.61, y1: 0.03, y2: 0.48 }, { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },

Corner radius

The cornerRadius property in the chart series is used to customize the corner radius for 100% stacked bar series. This allows you to create 100% stacked bars with rounded corners, giving your chart a more polished appearance. You can customize each corner of the 100% stacked bars using the topLeft, topRight, bottomLeft, and bottomRight properties.

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 stackedData = [
    { x: 2000, y: 0.61, y1: 0.03, y2: 0.48},
    { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
    { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
    { x: 2003, y: 1,    y1: 0.09, y2: 0.61 }, 
    { x: 2004, y: 1.19, y1: 0.14, y2: 0.63 },

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 stackedData = [
    { x: 2000, y: 0.61, y1: 0.03, y2: 0.48},
    { x: 2001, y: 0.81, y1: 0.05, y2: 0.53 },
    { x: 2002, y: 0.91, y1: 0.06, y2: 0.57 },
    { x: 2003, y: 1,    y1: 0.09, y2: 0.61 }, 
    { x: 2004, y: 1.19, y1: 0.14, y2: 0.63 },
    { x: 2005, y: 1.47, y1: 0.20, y2: 0.64 },
    { x: 2006, y: 1.74, y1: 0.29, y2: 0.66 },
