Radar Graph

Radar graphs are essentially Line graphs that use a radial grid to display data items. Scale value grid lines in a Radar graph circle around a central point, which represents zero. Higher data values are farther from the center point.

Grids for Radar graphs are equilateral polygons, with each category plotted at a vertex of the polygon. Thus, when three categories are used in a Radar graph, the grid is triangular; when eight categories are used, the grid is octagonal.

The area inside of the polygon for each series is colored translucently. This coloring makes it possible to see the "size" of a data series while still being able to see the other data series in the graph.

Powering Radar graphs

Radar graphs require three columns or rows of data from your DataSet—one for categories (generally dates), one for values, and one for series data. At least three categories must be present in a Radar graph. For information about value, category, and series data, see Understanding Chart Data.

In the Analyzer, you choose the columns containing the data for your Radar graph. For more information about choosing data columns, see Applying DataSet Columns to Your Chart.

For more information about formatting charts in the Analyzer, see KPI Card Building Part 2: The Analyzer.

The following graphic shows you how the data from a typical column-based spreadsheet is converted into a Radar graph:

Customizing Radar graphs

You can customize the appearance of a Radar graph by editing its Chart Properties. For information about all chart properties, see Chart Properties. Unique properties of Radar graphs include the following. You can click a thumbnail image to see a larger image.




Radar Settings > Series Transparency

Determines the transparency for the fill areas in a Radar graph. You can specify any value between 0 and 100, where 0 means the fill areas are completely opaque and 100 means they have no fill at all. In the example, the transparency has been set to 20.

Category Scale > Wrap Width

Allows you to specify the number of pixels at which category labels will wrap in Radar graphs.
