The JavaScript 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.
Mark data points with built-in shapes: circles, rectangles, ellipses, vertical lines, horizontal lines, diamonds, triangles, pentagons, crosses, and pluses. In addition to these shapes, use images to make the points more attractive.
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.
Handle missing data elegantly with empty points support.
The JavaScript range area chart can be transposed vertically to view the data from a different perspective.
Customize the color and border of the range area chart using built-in APIs.
Enable zooming and panning when dealing with large amounts of data to focus on particular ranges.
Easily get started with JavaScript Range Area using a few simple lines of JS code, as demonstrated below. Also explore our JavaScript Range Area Chart Example that shows you how to render and configure the range area chart component.
import { Chart,RangeAreaSeries, DateTime } from '@syncfusion/ej2-charts';
Chart.Inject(Chart, RangeAreaSeries, DateTime);
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);
}
let chart: Chart = new Chart({
primaryXAxis: {
valueType: 'DateTime'
},
series:[{
type: 'RangeArea',
dataSource: series1,
xName: 'x', high: 'high', low: 'low',
}
],
}, '#Chart');<!DOCTYPE html>
