Angular Range Area Chart & Graph | Angular Charts

Overview

The Angular range area chart is used to show variation in data values for a given time. It is like the area series, except that the area between the high and low ranges is filled.

Marker

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.

Empty/null data point

Handle missing data elegantly with empty points support.

Vertical chart

The Angular range area chart can be transposed vertically to view the data from a different perspective.

Customization

Customize the color and border of the range area chart using built-in APIs.

Zoom and pan

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

Angular Range Area Chart Code Example

Easily get started with Angular Range Area using a few simple lines of JS code, as demonstrated below. Also explore our Angular Range Area Chart Example that shows you how to render and configure the range area chart component.

html
ts
<ejs-chart style='display:block' id='chartcontainer'  [primaryXAxis]='primaryXAxis'>
<e-series-collection>
     <e-series [dataSource]='data' type='RangeArea' drawType= "Line" xName='x' high='high' low ='low'> </e-series>    
</e-series-collection>
</ejs-chart>
//app.component.ts

import { Component } from '@angular/core';
export class AppComponent { 
  public data: Object[];
  constructor () {
    let series1: Object[] = [];
    let value: number = 35;
    let point1: Object;

   for (let i: number = 1; i < 360; i++) {
    if (Math.random() > .5) {
        value += Math.random();
    } else {
        value -= Math.random();
    }
    point1 = {
        x: new Date(2015, 0, i),
        high: value, low: value - 10
    };
    series1.push(point1);
   }
    this.data = series1;
} 
 
//Initializing Primary X Axis
public primaryXAxis: Object = {
    valueType: 'DateTime',
     
};
}
