A Radar chart, also known as a spider chart or a star chart because of its appearance, plots the values of each category along a separate axis that starts in the center of the chart and ends on the outer ring.
Radar charts are used to display how a number of results compare with a certain defined target. Radar charts are not suitable if it is necessary to have accurate readings of the chart because of its inherent nature to depict very detailed values.
You must select the Axis dimension and the Legend in order to create a Radar chart. The Axis dimension comprises the metrics that represent a single data point for each element. The selected elements in the Legend represent the individual polygons on the radar. In addition, you can apply lists to both the dimensions.
Radar charts compare the aggregate values of multiple data series.
Creating radar charts
1. On the toolbar, select + New Page from the Pages drop down, or on the Filters and Settings pane, select the Pages tabbed page and then click the + icon to create a new page.
2. Click
the 
icon in the chart area
and then select the Advanced tabbed page.
3. Select
the Radar chart type or click the
icon at the top right corner of the chart area and then
select Radar to create a Radar chart.
4. From the Dimensions pane, specify a radarDim for the Radar chart.
5. Specify a Measure for your chart.
Optionally, specify a Page Dimension for your chart.
6. In the Filters and Settings pane, select any of the following:
▪ Filters tabbed page to browse the chart dimensions using the Dimensions Browser.
▪ Pages to view all pages in the current report as thumbnails.
▪ Settings to define drill through, page, or report properties for the chart.
Before creating a visualization, it is recommended to select the Dimension Browser view by selecting the Filters tabbed page from the Filters and Settings pane. The Dimensions Browser enables you to easily drag and drop Dimensions or Measures from the Dimensions pane (depending on the chart type) into Dimensions, Measures, Legend, or Browsing Dimensions of the Dimension Browser.
