To render a pyramid series, use the series type as Pyramid and inject PyramidSeries module into the @NgModule.providers.

To known about pyramid, you can check on this video:

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series type='Pyramid' [dataSource]='pyramidData' xName='x' yName='y'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    public enableSmartLabels: boolean;
    ngOnInit(): void {
        this.pyramidData = pyramidData;
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PyramidSeriesService,CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PyramidSeriesService,CategoryService, AccumulationDataLabelService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Mode

The Pyramid chart supports linear and surface modes of rendering. The default type of the pyramidMode is linear.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series type='Pyramid' pyramidMode='Surface' [dataSource]='pyramidData' xName='x' yName='y' [dataLabel]='datalabel'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    ngOnInit(): void {
        this.pyramidData = pyramidData;
    }
}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PyramidSeriesService,CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PyramidSeriesService,CategoryService, AccumulationDataLabelService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Size

The size of the pyramid chart can be customized by using the width and height properties.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series width='60%' height='80%' type='Pyramid' [dataSource]='pyramidData' xName='x' yName='y'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    ngOnInit(): void {
        this.pyramidData = pyramidData;
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PyramidSeriesService,CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PyramidSeriesService,CategoryService, AccumulationDataLabelService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Gap Between the Segments

Pyramid chart provides options to customize the space between the segments by using the gapRatio property of the series. It ranges from 0 to 1.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Pyramid' [dataSource]='pyramidData' xName='x' yName='y' [gapRatio]="gapRatio"></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    public gapRatio: number = 0.2;
    ngOnInit(): void {
        this.pyramidData = pyramidData;
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PyramidSeriesService,CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PyramidSeriesService,CategoryService, AccumulationDataLabelService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Explode

Points can be exploded on mouse click by setting the explode property to true. You can also explode the point on load using explodeIndex. Explode distance can be set by using explodeOffset property.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container">
        <e-accumulation-series-collection>
            <e-accumulation-series type='Pyramid' [dataSource]='pyramidData' xName='x' yName='y' [explode]='explode' [explodeAll]='explodeAll'
            [explodeIndex]='explodeIndex'></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    public explode: boolean;
    public explodeIndex: number;
    public explodeAll: boolean;
    ngOnInit(): void {
        this.explode = true;
        this.explodeIndex = 3;
        this.explodeOffset = '30px';
        this.explodeAll = false;
        this.pyramidData = pyramidData;
    }

}

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { AccumulationChartModule } from '@syncfusion/ej2-angular-charts';
import { PyramidSeriesService,CategoryService, AccumulationDataLabelService } from '@syncfusion/ej2-angular-charts';

/**
 * Module
 */
@NgModule({
    imports: [
        BrowserModule, AccumulationChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [PyramidSeriesService,CategoryService, AccumulationDataLabelService]
})
export class AppModule { }

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

Customization

Individual points can be customized using the pointRender event.

app.component.ts

import { Component, OnInit } from '@angular/core';
import { pyramidData } from 'datasource.ts';
import { IAccTextRenderEventArgs, IAccPointRenderEventArgs } from '@syncfusion/ej2-charts';
@Component({
    selector: 'app-container',
    template:
    `<ejs-accumulationchart id="chart-container"  (pointRender)="onPointRender($event)">
        <e-accumulation-series-collection>
            <e-accumulation-series  type='Pyramid' [dataSource]='pyramidData' xName='x' yName='y' [dataLabel]='datalabel' [gapRatio]="gapRatio"
            ></e-accumulation-series>
        </e-accumulation-series-collection>
    </ejs-accumulationchart>`
})
export class AppComponent implements OnInit {
    public pyramidData: Object[];
    public gapRatio: number = 0.2;
    public onPointRender: Function;
    ngOnInit(): void {
        this.onPointRender = (args: IAccPointRenderEventArgs): void {
            if ((args.point.x as string).indexOf('Downloaded') > -1) {
                args.fill = '#D3D3D3';
            }
            else {
            args.fill = '#597cf9';
        }
        }
        this.pyramidData = pyramidData;
    }

}
