ASP.NET MVC Bar Chart Overview
The Telerik UI Bar Chart HtmlHelper for ASP.NET MVC is a server-side wrapper for the Kendo UI Bar Chart widget.
Bar Charts display data by using horizontal or vertical bars whose length varies according to their values. Bar Charts are suitable for displaying a comparison between several sets of data, for example, for showing a summary of unique and total site visitors over a period of time. The series are placed next to each other with predefined spacing between them.
