This example demonstrates a RadHtmlChart 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.
