100% Stacked Bar in Angular Chart component

19 Sep 202424 minutes to read

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:

  1. 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.

  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 the 100% 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'>

    ngOnInit(): void {
        this.chartData = stackedData;
        this.primaryXAxis = {

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'

    }

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.

        { x: 2009, y: 1.70, y1: 0.75, y2: 0.55 }
    ];

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.

Empty points

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

Mode
