Stacked Bar in Angular Chart component

28 Mar 202524 minutes to read

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:

  1. 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.

  2. Inject the StackingBarSeries module: Use the @NgModule.providers method to inject the StackingBarSeriesService module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering stacked bar series are available in your chart.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { BarSeriesService, StackingBarSeriesService, CategoryService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { stackedData } from './datasource';
@Component({
imports: [
         ChartModule
    ],

providers: [ BarSeriesService, StackingBarSeriesService, CategoryService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='StackingBar' xName='x' yName='y' name='Apple'></e-series>
            <e-series [dataSource]='chartData' type='StackingBar' xName='x' yName='y1' name='Orange'></e-series>
            <e-series [dataSource]='chartData' type='StackingBar' xName='x' yName='y2' name='Wastage'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    primaryYAxis: any;
    ngOnInit(): void {
        this.chartData = stackedData;
        this.primaryXAxis = {
            valueType: 'Category',
            title: 'Months'
        };
        this.title = 'Sales Comparison';
    }

}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let stackedData: Object[] = [
        { 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: 'Nov', y: 40, y1: 41, y2: -6 }, 
        { x: 'Dec', y: 42, y1: 42, y2: -6.5 }
    ];

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.

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { BarSeriesService, StackingBarSeriesService, CategoryService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { stackedData } from './datasource';
@Component({
imports: [
         ChartModule
    ],

        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    primaryYAxis: any;
    ngOnInit(): void {
        this.chartData = stackedData;
        this.primaryXAxis = {

            title: 'Months'
        };
        this.title = 'Sales Comparison';
    }

}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let stackedData: Object[] = [
        { x: 'Jan', y: 6,  y1: 6,  y2: -1 }, 
        { x: 'Feb', y: 8 , y1: 8,  y2: -1.5 },

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.

import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { BarSeriesService, StackingBarSeriesService, CategoryService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { stackedData } from './datasource';
@Component({
imports: [
         ChartModule
    ],

providers: [ BarSeriesService, StackingBarSeriesService, CategoryService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>

        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    primaryYAxis: any;
    ngOnInit(): void {
        this.chartData = stackedData;
        this.primaryXAxis = {
            valueType: 'Category',
            title: 'Months'
        };
        this.title = 'Sales Comparison';    
    }

}
import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));
export let stackedData: Object[] = [
        { 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 }
    ];

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.

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.

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 define how empty or missing data points are handled in the series. The default mode for empty points is Gap.

Stack Labels Customization

Stack labels have various properties for customization to enhance the visual based on your requirements:

  • visible - Specifies whether stack labels are visible. Setting to true will display the labels. Default is false.
  • fill - Defines the background color of the stack labels. Accepts valid CSS color strings (hex, RGBA, etc.). Default is transparent.
  • format - Formats the text displayed in the stack labels. Supports placeholders like {value}. Default is null.
  • angle - Specifies the rotation angle for stack labels in degrees. Default is 0.
  • rx - Defines the rounded corner radius along the X-axis (horizontal direction) for the stack label background. Default is 5.
  • ry - Defines the rounded corner radius along the Y-axis (vertical direction) for the stack label background. Default is 5.
  • margin - Configures the margin around the stack label (left, right, top, and bottom).
  • border - Configures the appearance of the stack label’s border.
  • font - Customizes the stack label text, including font size, color, style, weight, and family.

Corner Radius

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

Point Corner Radius

We can customize the corner radius for individual points in the chart series using the pointRender event by setting the cornerRadius property in its event argument.
