Overview

The JavaScript Histogram chart is a bar (column) chart used for frequency distribution where the widths of bars are proportional to classes into which variables have been divided and the heights of the bars are proportional to class frequencies.


Distribution curve

Provides a graphical representation of the normal distribution of data.


Marker

Mark data points with built-in shapes such as 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 its given angle.


Vertical chart

The JavaScript Histogram Chart can be transposed vertically to view the data in a different perspective.


Customization

Customizes the color and border of the histogram chart using built-in APIs to make it visually unique.


JavaScript Histogram Chart Code Example

Easily get started with JavaScript Histogram Chart by using a few lines of HTML and JS code, as demonstrated below. Also explore our JavaScript Histogram Chart Example that shows how to render and configure the chart.

import { Chart, HistogramSeries} from '@syncfusion/ej2-charts';
Chart.Inject(HiloOpenCloseSeries);
let chartData: Object[] = [];
    let points: number[] = [5.250, 7.750, 0, 8.275, 9.750, 7.750, 8.275, 6.250, 5.750,
