The ASP.NET Web Forms Sparkline charts control, 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 toolkit to display data when there is space constraints, for example, viewing on the mobile device, placing inside a grid cell, etc.
The ASP.NET Web Forms Sparkline charts control supports five types of sparklines (line, column, area, win-loss, and pie) to show the data trends.
Use line sparkline to represent patterns and trends in data, such as seasonal effects, large changes, and turning points over a period of time.
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.
Show different values of two or more subjects using column sparkline; use vertical bars to represent different values.
Use win-loss sparkline to show if each value is positive, negative, or zero to visualize win/loss scenarios such as results in games.
A pie sparkline is a circular graph that is divided into slices to illustrate numeric proportions.
Configure and customize axes in the sparkline graphs to show the origin and range of data points.
Denote data usage in ASP.NET Web Forms Sparkline charts by highlighting and customizing special data points, such as first, last, high, low, and negative points.
The marker highlights data points in a line and area sparklines and makes these sparklines more readable.
The interactive sparkline charts provide options to display details about data point values through a tooltip when hovering the mouse over a data point.
Highlight a particular region in the ASP.NET Web Forms Sparkline charts control using range band to show the range of safe values. By setting the minimum and maximum ranges for a range band, the outliers can easily be identified.
The interactive Sparkline Control also supports touch interactions.
All the sparkline features will work on touch devices with zero configuration. Use the touch features such as tooltip and track line without any customization.
You can view the ASP.NET Web Forms Sparkline charts control on various devices. You can also hide specific elements in a sparkline for particular screen sizes by making minimal changes to the events.
You can render Sparkline Control in all the modern browsers.
