The HTML5 JavaScript Sparkline Charts which is also known as inline graph or tiny charts is a data visualization tool that helps represent trends and variations associated with a measurement—such as average temperature or stock market activity—in a simple, lightweight, and condensed manner. This is a replacement for chart when there are space constraints, for example, viewing on the mobile device, placing inside a grid cell, etc.

Sparkline types

JavaScript Sparkline Charts supports five types of sparklines (line, column, area, win-loss, and pie) to show data trends.

Line sparkline

Use line sparkline to represent patterns and trends in data, such as seasonal effects, large changes, and turning points over a period of time.

JavaScript sparkline charts rendered in area type

Area sparkline

An area sparkline is a line sparkline with the area between its points colored. Use this when the magnitude of the trend is to be communicated rather than individual data values.

JavaScript sparkline charts rendered in column type

Column sparkline

A column sparkline is designed to show different values of two or more subjects; use vertical bars to represent the different values.

JavaScript sparkline charts rendered in win-loss type

Win-loss sparkline

Use win-loss sparkline to show if each value is positive, negative, or zero to visualize win/loss scenarios such as results in games.

Pie sparkline

A pie sparkline is a circular graph that is divided into slices to illustrate numeric proportions.

Axis value types

JavaScript sparkline charts control offers different axes types like numeric, category, and date-time to plot any type of data in the sparkline.

Axis customization

Configure and customize the axis in the sparkline graphs to show the origin and range of the data points.
