JavaScript Histogram Charts & Graphs | HTML5

Overview

Histogram chart is a bar (column) chart used for frequency distribution in which the widths of the 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

Marks 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 point 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 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.
