Angular Spline Chart connects data points with smooth lines. It uses numeric, category, date-time, and logarithmic axes to plot data.

Multi series

Allows you to plot multiple series in a single chart to compare different data sets. Enabling legend and tooltip gives more information about the individual series.


Mark data points with built-in shapes: circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, and pentagons. In addition to these shapes, use images to make the points more attractive.

Data label

Data labels display information about data points. Add a template to display data labels with HTML elements such as images, DIV, and spans for more informative data labels. You can rotate a data label by a given angle.

Multiple axes

Use multiple axes to plot different data sets that vary widely from each other.

Zoom and pan

Enable zooming and panning when dealing with large amounts of data to focus on particular ranges.

Dynamic spline chart

Create and update the spline chart with live data that changes in seconds or minutes.

Empty/null data point

Handle missing data elegantly with empty points support.

Vertical chart

The Angular Spline Chart can be transposed vertically to view the data from a different perspective.


Customize the color, thickness, and dash array of the spline chart using built-in APIs.

Angular Spline Chart Code Example

<ejs-chart style='display:block' id='chartcontainer'  [primaryXAxis]='primaryXAxis'>
    <e-series [dataSource]='data' type='Spline' xName='x' yName='y'> </e-series>    

import { Component } from '@angular/core';
export class AppComponent {
  public data: Object[] = [
                { x: 'Sun', y: 15 }, { x: 'Mon', y: 22 },
                { x: 'Tue', y: 32 },
                { x: 'Wed', y: 31 },
                { x: 'Thu', y: 29 }, { x: 'Fri', y: 24 },
                { x: 'Sat', y: 18 },
//Initializing Primary X Axis
public primaryXAxis: Object = {
    valueType: 'Category',


import { ChartModule } from '@syncfusion/ej2-ng-charts';
