    Radar Area Chart
    In This Topic

    The Radar area plot arranges categories on the circumference of a circle and connects the corresponding points with straight lines. The data values are plotted radially and are connected with straight lines resulting in a polygon shape. Radar Area plots are generally used to display ordinal variables across different category ranges.

    Radar Area Plot with Single Value

    A single value radar area chart shows measurements of one variable. The Create Radar Area Chart with Single Value walkthrough showcases the average budget for different movie genres.

    Radar Area Plot with Multiple Values

    A multiple values radar chart lets you split data values into subcategories for finer analysis. The Create Radar Area Chart with Multiple Values walkthrough showcases the average movie budget in a country for different movie genres.

    Radial Area Plot Properties

    The 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.

    Appearance

    BackgroundColor

    Indicates the color used to fill the chart area.

    Common

    Action

    The action to perform when the plot is clicked. The action can be a hyperlink, a bookmark, or a drill-through.

    Labels

    The data labels for each chart.

    LineStyle

    The line style for the borders. Includes LineColor, LineStyle, and LineWidth properties for the customization.

    Name

    The name of the plot. By default, a chart containing a single plot has the plot name as 'Plot1'.

    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:

    LineAspect

    The Line Aspect determines the line style that connects data points.

    Opacity

    The Opacity determines the opacity of areas filled with color. The Opacity is specified in percentage. 0% means that they are entirely transparent, and 100% means they are opaque.

    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 plot. A full rotation makes 360 degrees.

    UnpivotData

    Determines whether to display multiple data fields as a single data field. By default, the property is set to 'False'. 

    Encodings

    Category Encoding 

    The Category Encoding of a plot is a set of properties that determine the period over which the plot generates connected data points representing those above 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 Area 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:

    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 Area plots, 'Simple' is acceptable.

    Value

    The Value property is the collection and usually takes a bound field. However, the Area 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.
