Overview

The Radar Range Chart is a type of circular graph that plots data points as a filled area between two measure values. This chart can be used to plot a KPI or dataset having two metric/measure values, such as high and low stock prices, for each dimension value.

Like other range charts, you can set the Fill brush for the plotted area or control the Stroke Thickness of the area border by setting properties of the chart series.

The grid lines in the plotting area can be displayed as polygons or circles. Other notes:

  • This chart is represented by the DashboardRadarRangeChart class, which has common chart properties and interactions.
  • This chart accepts two metric values from each KPI or contextual metric added to it, for each X axis dimension value.
  • In another circular chart, make a series Radar Range by setting the Chart Type property of the series to RadarRange.
  • When a series is Radar Range, its type and properties are those of the DashboardRadarRangeDataSeries class.

Features

The Radar Range Chart has features in common with the Radar Line Chart, including Plotting Area Style, Radar Size, Minimum Radar Size, and Start Angle.

Toolbox

You can access the Radar Range Chart type from the Dashboard Designer Toolbox, under the Data Controls\Charts folder.

Start and End metric settings

Consider a KPI with two measure values as shown below.

When you add this KPI to a Radar Range chart, the Data Settings Configuration wizard appears. In the second step of this wizard, you must select the Start and End metrics that define the range.

Overlapping ranges

When you add multiple series to a radar range chart, the ranges may overlap. To ensure you can still see each range, one approach is to set the following properties of a chart series:

  • Increase the Z-Index value of a series to make the corresponding range appear on top. For example, you may want to do this for the series with smaller metric values.
  • For the series on top, lower its Opacity so that the range(s) underneath can be seen. Alternatively, you can set the Fill brush of the top series to be semi-transparent.
