Column Chart

  • Product Sales Column Chart Settings

This example demonstrates an ASP.NET AJAX Chart control, configured as a Column Chart (it uses ColumnSeries). The Column Chart type for ASP.NET visualizes the data as vertical bars and it's very similar to the Bar Chart. The height of each vertical bar varies according to its value. ASP.NET Column Charting is helpful when you need to show a comparison between several data sets. With RadHtmlChart you have many options that enable you to change the appearance of your column chart and fully customize it.

The distance between the series items and the series categories can be configured via the properties Gap and Spacing of the series since the Q1 2014 release.
