Axis labels in Angular Chart component

3 Feb 202624 minutes to read

Smart axis labels

When axis labels overlap due to limited space or dense data points, the labelIntersectAction property can be used to control how the labels are rendered. This helps improve readability by automatically adjusting label visibility or orientation.

When setting labelIntersectAction as Hide, overlapping labels are hidden to avoid visual clutter.

app.component.ts

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



import { Component, OnInit } from '@angular/core';

@Component({
imports: [
         ChartModule
    ],

providers: [ CategoryService, ColumnSeriesService, LineSeriesService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" width='450px' [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Column' xName='x' yName='y' name='Internet'></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: "South Korea", y: 39.4 }, { x: "India", y: 61.3 }, { x: "Pakistan", y: 20.4 },
                { x: "Germany", y: 65.1 }, { x: "Australia", y: 15.8 }, { x: "Italy", y: 29.2 },
                { x: "France", y: 44.6 }, { x: "Saudi Arabia", y: 9.7 }, { x: "Russia", y: 40.8 },
                { x: "Mexico", y: 31 }, { x: "Brazil", y: 75.9 }, { x: "China", y: 51.4 }
        ];
        this.primaryXAxis = {
           title: 'Countries',
           valueType: 'Category',
           labelIntersectAction: 'Hide'
        };
        this.primaryYAxis = {
           minimum: 0, maximum: 80, interval: 10,
           title: 'People(in millions)'
        };
        this.title = 'Internet Users';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

When setting labelIntersectAction as Rotate45, the labels are rotated by 45 degrees to reduce overlap.

app.component.ts

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

    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    ngOnInit(): void {
        this.chartData = labelData;
        this.primaryXAxis = {
           title: 'Countries',
           valueType: 'Category',
           labelIntersectAction: 'Rotate45'
        };
        this.primaryYAxis = {
           minimum: 0, maximum: 80, interval: 10,
           title: 'People(in millions)'
        };
        this.title = 'Internet Users';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

When setting labelIntersectAction as Rotate90, the labels are rotated vertically to maximize space utilization.

app.component.ts

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

           title: 'Countries',
           valueType: 'Category',
           labelIntersectAction: 'Rotate90'
        };
        this.primaryYAxis = {

bootstrapApplication(AppComponent).catch((err) => console.error(err));

Axis labels positioning

By default, axis labels are positioned outside the axis line. Labels can also be placed inside the axis line using the labelPosition property, which is useful when optimizing space within the chart area.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'



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

providers: [ CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService],
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='Column' xName='country' yName='gold' name='Gold' ></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis: any;
    
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category',
           title: 'Countries',
           labelPosition: 'Inside'
        };
        this.title = 'Olympic Medals';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Multilevel labels

Multiple levels of labels can be displayed on an axis using the multiLevelLabels property. This feature is useful for grouping related categories and improving data interpretation. The following configuration options are available:

• Categories
• Overflow
• Alignment
• Text style
• Border

Note: To use multilevel label feature, inject MultiLevelLabel into the @NgModule.providers.

Categories

Using the categories property, the start, end, text, and maximumTextWidth values of multilevel labels can be configured to define the label range and content.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'

    public title?: string;
    public legendSettings: Object = { visible: false};
    primaryYAxis: any;
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category',
           multiLevelLabels:[{ categories: [
                        {
                            //Start and end values of the multi-level labels accepts number, date and sring values
                            start: -0.5,
                            end: 3.5,
                            //Multi-level label's text.
                            text: 'Half Yearly 1',

                        },
                        { start: 3.5, end: 7.5, text: 'Half Yearly 2' },
                    ]}]
        };
        this.title = 'Olympic Medals';
    }

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Overflow

Using the overflow property, multilevel labels can be configured to either trim or wrap when the text exceeds the available space.

app.component.ts

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

                        { start: 3.5, end: 7.5, text: 'Half Yearly 2' }],
               textStyle:{size:'18px', color:'Red'}
           }]
        };
        this.title = 'Olympic Medals';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Border customization

Using the border property, the width, color, and type of the multilevel label border can be customized. The supported border types are Rectangle, Brace, WithoutBorder, WithoutTopBorder, WithoutTopandBottomBorder, and CurlyBrace.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'

    public chartData?: Object[];
    public title?: string;
    public legendSettings: Object = { visible: false};
    primaryYAxis: any;
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category',
           multiLevelLabels:[{
               categories: [{start: -0.5, end: 3.5, text: 'Half Yearly 1' },
                        { start: 3.5, end: 7.5, text: 'Half Yearly 2' }],
               border:{type:'Brace', color:'Blue', width: 2},

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Edge label placement

Labels with long text at the edges of an axis may appear partially outside the chart area. To avoid this, use the edgeLabelPlacement property in the axis. This property moves the label inside the chart area or hides it for better appearance. By default, the edgeLabelPlacement property is set to Shift, ensuring that labels are repositioned inside the chart area to prevent overlap.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule } from '@syncfusion/ej2-angular-charts'
import { DateTimeService, LineSeriesService, DateTimeCategoryService, StripLineService} from '@syncfusion/ej2-angular-charts'



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

})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    public legendSettings: Object = { visible: false};
    ngOnInit(): void {
        this.chartData = dateData;
        this.primaryXAxis = {
            valueType: 'DateTime',
            title: 'Sales Across Years',
            labelFormat: 'yMMM',
            edgeLabelPlacement: 'Shift',
            minimum: new Date(2000, 6, 1),
            maximum: new Date(2010, 6, 1)
        };
        this.primaryYAxis = {
           title: 'Sales Amount in millions(USD)'
        };
        this.title = 'Average Sales Comparison';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Trim using maximum label width

You can trim the label using enableTrim property and width of the labels can also be customized using maximumLabelWidth property in the axis, the value maximum label width is 34 by default.

Labels customization

The labelStyle property of an axis provides options to customize the color, font-family, font-size, and font-weight of axis labels.

To known more about labels customization, you can check on this video:

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'



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

providers: [ CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'
    [legendSettings]='legendSettings'>

})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    public legendSettings: Object = { visible: false};
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category',
           title: 'Countries'
        };
        this.primaryYAxis = {
           minimum: 0, maximum: 80,
           interval: 20, title: 'Medals',
           labelFormat: '${value}K',
           titleStyle: {

           }
        };
        this.title = 'Olympic Medals';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Label rotation

The axis labels can be rotated based on the labelRotation property in primaryXAxis.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'



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

providers: [ CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'
    [legendSettings]='legendSettings'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Column' xName='country' yName='gold' name='Gold' ></e-series>
            <e-series [dataSource]='chartData' type='Column' xName='country' yName='silver' name='Silver'></e-series>
            <e-series [dataSource]='chartData' type='Column' xName='country' yName='bronze' name='Bronze' ></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public primaryYAxis?: Object;
    public legendSettings: Object = { visible: false};
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category', labelRotation: 90,
           title: 'Countries'
        };
        this.primaryYAxis = {
           minimum: 0, maximum: 80,
           interval: 20, title: 'Medals',
           labelFormat: '${value}K',
           titleStyle: {
            size: '16px', color: 'grey',
            fontFamily : 'Segoe UI', fontWeight : 'bold'
           },
           labelStyle: {
            size: '14px', color: 'blue',
            fontFamily : 'Segoe UI', fontWeight : 'bold'
           }
        };
        this.title = 'Olympic Medals';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Customizing specific point

Specific axis label text can be customized using the axisLabelRender event, which allows conditional formatting or dynamic text updates during label rendering.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'



import { Component, OnInit } from '@angular/core';
import { categoryData } from './datasource';
import { IAxisLabelRenderEventArgs } from '@syncfusion/ej2-angular-charts';
@Component({
imports: [
         ChartModule
    ],

providers: [ CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title' (axisLabelRender) = 'axisLabelRender($event)'
    [legendSettings]='legendSettings'>
        <e-series-collection>
            <e-series [dataSource]='chartData' type='Column' xName='country' yName='gold' name='Gold' ></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public legendSettings: Object = { visible: false};
    primaryYAxis: any;
    public axisLabelRender(args : IAxisLabelRenderEventArgs ): void {
        if(args.text === 'France') {
            args.labelStyle.color = 'Red';
        }
    };
    ngOnInit(): void {
        this.chartData = categoryData;
        this.primaryXAxis = {
           valueType: 'Category',
           title: 'Countries'
        };
        this.title = 'Olympic Medals';
    }

}

main.ts

import { bootstrapApplication } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import 'zone.js';
bootstrapApplication(AppComponent).catch((err) => console.error(err));

Line break support

The line break feature is used to display long axis label text across multiple lines. In the following example, the x value in the data source contains long text, which is split into two lines using the <br> tag.

app.component.ts

import { NgModule } from '@angular/core'
import { BrowserModule } from '@angular/platform-browser'
import { ChartModule} from '@syncfusion/ej2-angular-charts'
import { CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService} from '@syncfusion/ej2-angular-charts'




import { Component, OnInit } from '@angular/core';
import { Browser } from '@syncfusion/ej2-base';
@Component({
imports: [
         ChartModule
    ],

providers: [ CategoryService, BarSeriesService, ColumnSeriesService, LineSeriesService,LegendService, DataLabelService, MultiLevelLabelService, SelectionService],
standalone: true,
    selector: 'app-container',
    template: `<ejs-chart id="chart-container" [primaryXAxis]='primaryXAxis'[primaryYAxis]='primaryYAxis' [title]='title'>
        <e-series-collection>
            <e-series [dataSource]='data' type='Bar' xName='x' yName='y' width=2 ></e-series>
        </e-series-collection>
    </ejs-chart>`
})
export class AppComponent implements OnInit {
    public primaryXAxis?: Object;
    public primaryYAxis?: Object;
    public chartData?: Object[];
    public title?: string;
    public data: Object[] = [
        { x: 'Germany', y: 72, country: 'GER: 72' },
        { x: 'Russia', y: 103.1, country: 'RUS: 103.1' },
        { x: 'Brazil', y: 139.1, country: 'BRZ: 139.1' },
        { x: 'India', y: 462.1, country: 'IND: 462.1' },
        { x: 'China', y: 721.4, country: 'CHN: 721.4' },
        { x: 'United States<br>Of America', y: 286.9, country: 'USA: 286.9' },
        { x: 'Great Britain', y: 115.1, country: 'GBR: 115.1' },
        { x: 'Nigeria', y: 97.2, country: 'NGR: 97.2' }
    ];
    ngOnInit(): void {
        this.primaryXAxis = {
        title: 'Country',
        valueType: 'Category',
        majorGridLines: { width: 0 },
        enableTrim: false,
        };
        this.primaryYAxis = {
        minimum: 0,
        maximum: 800,
        labelFormat: Browser.isDevice ? '{value}' : '{value}M',
        edgeLabelPlacement: 'Shift',
        majorGridLines: { width: 0 },
        majorTickLines: { width: 0 },
        lineStyle: { width: 0 },
        labelStyle: {
            color: 'transparent'
        }
        };
        this.title = 'Internet Users – 2016';
    }

bootstrapApplication(AppComponent).catch((err) => console.error(err));

Maximum labels

MaximumLabels property is set, then the labels will be rendered based on the count in the property per 100 pixel. If you have set range (minimum, maximum, interval) and maximumLabels, then the priority goes to range only. If you haven’t set the range, then we have considered priority to maximumLabels property.

Axis label template

The axis label template allows axis labels to be customized using HTML content. This enables conditional styling and the inclusion of dynamic elements such as icons, images, or additional contextual data. This customization is enabled by setting the template content in the labelTemplate property of the AxisModel.

app.component.ts
