Radar Scatter and Radar Bubble charts are useful in showing ordered measurements of one or two variables across a category range. Radar Scatter and Radar Bubble plots arrange categories on a circle and link the corresponding points with straight lines. Data values are represented by value points called Symbols. The symbol size in a Radar Bubble plot can represent extra information about the data point. In Radar and Radar Bubble charts, the symbols are laid out along the radial lines. The major difference between the Radar Scatter plot and Radar Bubble plot is that the former visualizes a single variable measurement, while the latter encodes the size of data points.

Simple Radar Scatter Chart

A Simple Radar Scatter chart visualizes measurements of a single variable. For instance, the simple radar bubble plot can be used to display the average monthly temperature and precipitation in Paris, France.

Simple Radar Bubble Chart

A radar bubble chart encodes surplus data using data point sizes. For instance, the simple radar bubble plot can be used to display the average monthly temperature and precipitation in Paris, France. See Create Simple Radar Bubble Chart walkthrough to learn how to create this chart.

Multi-Category Radar Scatter and Bubble Charts

A Multi-Category Radar Scatter and Bubble charts can be used to configure Radar Scatter and Bubble charts to split data values into subcategories and depict them with symbols' colors, shapes, or both. For instance, the Multi-Category Radar Scatter and Bubble charts can be used to depict the average monthly temperature in three European cities that are distinguished by data points' colors. See Create Multi-Category Radar Scatter Chart walkthrough to learn how to create this chart.

Radar Scatter and Bubble Plot Properties

The Radar Scatter Plot properties discussed below can be accessed from the Properties Panel on selecting the Chart > Plot from the Report Explorer. You can access some of the important properties from the Plot's Smart Panel too. See Chart Smart Panels topic for more information. Both the Properties Panel and the Smart Panel can be accessed by right-clicking the plot in the design area.

Tooltip Template

Contains the tooltip template settings. You can choose from the list of predefined settings or set your own in the Expression Editor.

Configurations

ClippingMode

The Clipping Mode determines how a plot extends within the plot area. The ClippingMode can be set to

• Fit: Utilizes the free space to fit the plots within the plot area.
• Clip: Clips off the excess area lengths toward the right or the bottom.
• None: Same as 'Fit' for Radar Scatter Plots.

Overlays

Overlays property is a collection for superimposing the data trend on a plot. For more information, see Trendlines topic.

Rules

Rules control the appearance of plots based on specified conditions. For more information on conditions, see Rules topic.

ShowNulls

Represents how null or empty values should be shown in the plot - Gaps (default), Connected, or Zeros.

StartAngle

Indicates the arc angle that defines the clockwise rotation of the chart. A full rotation makes 360 degrees.

SymbolOpacity

Represents the opacity value of symbol fill color.

Encodings

Category Encoding 

The Category Encoding of a Radar Scatter Plot is a set of properties that determine the period over which the plot generates connected data points representing the Data Values. The Category encoding includes the following properties.

Values

The Values property is the collection and takes the field as a category.

SortingField

The SortingField defines the order in which the categories are displayed. It takes the default same as the Values field, but you can also specify another field to sort the categories.

SortDirection

The SortDirection defines the ascending or descending order in which the categories should be sorted.

SortingAggregate

The SortingAggregate property specifies the aggregate to use for sorting the categories. 

Color Encoding

The Color Encoding enables the color legend of the Details or Category Encoding. It includes the following properties:

Aggregate

Aggregates the value of Color expression.

ShowValuesName

If set to True, the legend is displayed based on the value specified in Details encoding or Color encoding.

Values

The Values is the collection where the value of the Color expression is specified. However, the Radar Scatter Plots take the first item from the collection.

Details Encoding

The Details Encoding breaks down the data values into subcategories and produces additional groups. The Details property is the collection of items and each item includes the following properties that define the Details encoding:

• ExcludeNulls: This flag indicates whether dataset records with undefined details should be exempted from the visualization.
• Group: This property determines the area subsection arrangement of the plot.
  • Stack: You can use this value to configure a Stacked Radar Scatter Plot.
  • Cluster: You can use this value to configure area subsections that overlap each other.
  • None: Equals to Cluster.
• SortDirection: This property determines the sorting direction, ascending or descending in which the subcategories should be sorted.
• SortingAggregate: The SortingAggregate property specifies the aggregate to use for sorting the subcategories. 
• SortingField: It defines the order in which the subcategories are displayed.
• Values: The Values could be one or more bound field references, and the bound DataSet records with the same values of these fields come under the same subcategory.

Shape Encoding

The Shape Encoding enables the shape legend of the Details or Category Encoding in Radar Scatter charts. It includes the Aggregate function and shape expression, which is elaborated below:

Aggregate

To show aggregated values such as Average, Count, and Sum instead of individual values, specify an Aggregate function.

Value

The Value property is the collection and usually takes a bound field. However, the Radar Scatter plots take the first item from the collection.

Size Encoding

The Size Encoding enables the Aggregate function and Size expression in Radar Bubble charts. The Size Encoding works solely with numeric values and breaks down data values into ranges that determine the symbol size.

Values Encoding

The Values encoding specifies the data values and represents the collection of items and each item includes the following properties.

Type

The Type property provides 'Simple' and 'Complex' options to choose from. However, for Radar Scatter Plots, 'Simple' is acceptable.

Value

The Value property is the collection and usually takes a bound field. However, the Radar Scatter Plots take the first item from the collection.

Aggregate

To show aggregated values such as Average, Count, and Sum instead of individual values, specify an Aggregate function.

Text Encoding

The Text Encoding provides support of any dataset field in chart labels and tooltips and allows displaying additional info on the chart. When two text encodings are added, they are displayed by default with the ";" delimiter. A text encoding includes the following properties:

Aggregate

Aggregates the value of the Text expression.

Target

Specifies whether this text is for a Label or a Tooltip Label. The label format is controlled with the chart's Labels > Template property or Tooltip Template property.

The Template property can use both the predefined values and the added text encoding fields, for example:

Count:{Text0}
Sum:{valueField.value}

Template Key

A unique key, used in the chart plot's Labels > Template and Tooltip Template to access the text encoding value.

Value

A field, constant or expression to be displayed.
