The RadarChart is a two-dimensional chart of three or more quantitative factors represented on axes starting from the same point. This chart type is useful in making comparisons between units that depend on such quantitative factors/variables. The closer the point/column of the particular variable is to the center of the chart, the lower its value is. The nearest the point/column of the particular variable is to the edge of the chart, the higher its value is.
RadHtmlChart supports three types of Radar Series. They are only different in the graphical primitives that are drawn. The primitives are a poly line, column and polygon respectively.
RadarAreaSeries — in this series type the data points are connected with straight line segments that enclose a filled area.
RadarColumnSeries — this series type is represented on the chart as data columns whose height varies according to their value.
RadarLineSeries — this series type is represented on the chart as data points connected with straight line.
