You can use numeric axis to represent numeric values of data in chart. By default, the valueType of an axis is Double.

To known about numeric axis, you can check on this video:

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';

@Component({
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Area' xName='x' yName='y' name='England'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    ngOnInit(): void {
        this.chartData = [
    { x: 1, y: 7 }, { x: 2, y: 1 }, { x: 3, y: 1 }, { x: 4, y: 14 }, { x: 5, y: 1 }, { x: 6, y: 10 },
    { x: 7, y: 8 }, { x: 8, y: 6 }, { x: 9, y: 10 }, { x: 10, y: 10 }, { x: 11, y: 16 }, { x: 12, y: 6 },
    { x: 13, y: 14 }, { x: 14, y: 7 }, { x: 15, y: 5 }, { x: 16, y: 2 }, { x: 17, y: 14 }, { x: 18, y: 7 },
    { x: 19, y: 7 }, { x: 20, y: 10 }];
        this.title = 'England - Run Rate';
    }

}

Range

Range for an axis, will be calculated automatically based on the provided data, you can also customize the range of the axis using minimum, maximum and interval property of the axis.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Area' xName='x' yName='y' name='England'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    ngOnInit(): void {
        this.primaryXAxis = {
            valueType: 'Double',
            minimum: 1,
            maximum: 20,
            interval: 5,
            title: 'Overs'
        };
        this.chartData = chartData;
        this.title = 'England - Run Rate';
    }

}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { ChartModule } from '@syncfusion/ej2-angular-charts';
import { ColumnSeriesService, AreaSeriesService} from '@syncfusion/ej2-angular-charts';

/**

 */
@NgModule({
    imports: [
        BrowserModule, ChartModule
    ],
    declarations: [AppComponent],
    bootstrap: [AppComponent],
    providers: [ ColumnSeriesService, AreaSeriesService]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';

import 'zone.js';

Range Padding

Padding can be applied to the minimum and maximum extremes of the axis range by using the rangePadding property. Numeric axis supports following types of padding.

None
Round
Additional
Normal
Auto

Numeric - None

When the rangePadding is set to None, minimum and maximum of an axis is based on the data.

app.component.ts
app.module.ts
main.ts
import { Component, OnInit } from '@angular/core';
import { chartData } from './datasource';

@Component({
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Area' xName='x' yName='y' name='England'></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    ngOnInit(): void {
        this.chartData = chartData;
        this.primaryXAxis = {
            valueType: 'Double',
            title: 'Overs'
        };
        this.primaryYAxis = {
           title: 'Runs',
           valueType: 'Double',
           rangePadding: 'None'
        };
        this.title = 'England - Run Rate';
    }
