Radar Area
plots are useful to display ordinal measurements of a variable across a range of categories. A radar area plot arranges categories on a circle and connects the corresponding points with straight lines. Data values are represented by points laid out along radial lines and connected with straight or curved lines. The resulting shape is filled with a color.
A single value radar area plot visualizes measurements of a single variable.
For instance, the Radar Area Plot with Single Value Demo displays the average budget for several movie genres.
A multiple-area radar plot allows you to split data values into subcategories for more granular analysis. For instance, the Radar Area Plot with Multiple Areas Demo displays the average movie budget per country for several movie genres.
You can configure all these types using the Radar Area
plot template and its properties described in the following sections.
You can use the following demos to explore plot properties - open a link, toggle the Report explorer, select the Plot - Plot 1
node and use the Properties panel to modify the configuration.
You could also download the report files listed below and open them in the Standalone Report Designer.
If you add a chart into a report, set the plot type to Radar Area
on the first page of the Chart Wizard
, and click the Next
button, the wizard shows the Radar Area Settings
page that looks like the following:
The Data Values
section allows you to add one or more Data Values.
The Data Categories
section allows you to set the Category Encoding.
The Data Subcategories
section allows you to configure the Details Encoding.
The Radar Area plot's Values
collection determines data values that are displayed by data points connected by lines. The collection items consist of two properties:
The Value
is usually a bound field reference. The Properties Panel displays the Value
as the collection, but Radar Area
plots take the first item only. The Chart Wizard displays the Value
as Field
.
The Aggregate
is an optional function, such as Count
or Sum
, that reduces many field values into a single one.
For instance, all the demos listed above have the Value={Budget}, Aggregate=Average
Data Value.
The Category Encoding
of a Radar Area
plot is a set of properties that determine categories for which the plot generates connected data points representing those above Data Values
.
The Category
is usually a bound field reference. Bound DataSet Records with the same value of that field fall into the same category. For instance, the Radar Area Plot with Single Value Demo is bound to the Ratings
DataSet containing several fields, including the Genre
field, for each data record. The plot's Category
is set to {Genre}
expression. Therefore the plot goes through the Ratings
DataSet finds the distinct Genre
values and generates one category per genre. If you preview the demo output, you can see seven genres.
The Category Sorting
configuration determines the order of the category values appearance.
The Chart Wizard
offers the simplified editor of the Category Encoding
in the Data Categories
section:
A single Category Expression
displayed as Field
is available.
The Sorting
configuration of the Category Encoding
displays the Sort direction
property only. The Sort Expression
is automatically set to the Field
value.
The Details Encoding
allows you to break down those above Data Values
into subcategories for more granular analysis of changes.
The Details
property of a Radar Area
plot is the collection of items that determine these subcategories. Each item includes several properties:
The Values
is usually one or more bound field references. Bound DataSet Records with the same values of these fields fall into the same subcategory. For instance, in the Radar Area Plot with Multiple Areas Demo the Details
value is {Country}
. Consequently, the Average Budget
of each genre splits into the USA
and UK
subcategories that generate a data point.
The Exclude Nulls
flag indicates whether DataSet Records with an undefined Details Value
should be excluded from the visualization.
The Sorting
configuration determines the order of subcategories' appearance.
The Chart Wizard
offers the simplified editor of the Details Encoding
in the Data Subcategories
section:
A single Details Encoding
item is available.
A single Value
item displayed as Field
is available.
The Sorting
configuration of the Details Encoding
displays the Sort direction
property only. The Sort Expression
is automatically set to the Field
value.
The Colors Encoding
enables the color legend of the Details Encoding
and includes the Color
expression and the optional Color Aggregate
function that reduces many Color
values into a single one.
The plot calculates distinct Color Encoding
results for the subcategories produced by the Details Encoding
, converts them to fill colors of corresponding areas, and displays the match between colors and encoding results in the legend. Colors come from the Chart Palette.
For instance, the Radar Area Plot with Multiple Areas Demo uses the {Country}
expression for the Colors Encoding. Consequently, the report output shows the colors legend that matches countries with the fill color of corresponding areas.
Note: The Color
property is the collection, but the Radar Area
plot takes the first item only.
The following properties allow you to fine-tune the outfit of shapes that form the Radar Area
plot. You can see their effect in action by modifying the configuration of any area demo.
The Opacity
is a number in percentage that determine the opacity of areas filled with color. 100%
means they are opaque, and 0%
means that they are entirely transparent.
The Line Aspect
property determines the style of the line that connects data points.
Default
means the straight line
Spline
means the bezier curve
Step Center
, Step Left
and Step Right
are not applicable for a Radar Area plot.
The Show Nulls
property indicates the arrangement of data points for Null
values.
Gaps
means that the plot will not draw a line between a null data point and its previous and next points
Zero
means that null data points will be considered to have 0
value
Connected
means that the plot will connect the previous and the next points of a null point
The Clipping Mode
indicates the manner that the plot area draws a plot:
Fit
value means that the plot area should use all the available space to fit the plot
Clip
value means that the plot area cuts off the plot on the edge of its right or bottom padding
None
value equals to Fit
The line properties in the Style
section determine the appearance of lines that connect data points.
The color expression in the Background
section sets the fill color of areas and overwrites the Color Encoding
described earlier.
The Start Angle
is a number in arcdegree that defines the rotation of the plot clockwise. Full rotation is 360
degrees.
The Text Encoding
collection offers a way to configure radar area plots to display customized labels and tooltips on the data point. Each item within this collection has the following properties:
Values
: This is an expression that can reference the values of the bound fields.
Aggregate
: This optional function, such as Count
or Average
, can condense multiple field values into a single value, evaluated within the current detail or category context.
Template Key
: A string used within the Labels or Tooltip template to represent the text encoding item.
Target
: This property specifies whether the text encoding item is meant for the plot's labels or tooltips.
Adding items to the Text Encoding
collection allows automatic display of configured values in Labels or Tooltips, based on the Target
value of each item. To further customize the text of the labels and tooltips, you can employ the Tooltip Template
and Label Text Template
expressions.
Apart from Text Encoding items referenced by their keys, you can utilize the following pre-defined values:
{valueField.name}
: Represents the field name bound to a Data Value.
{valueField.value}
: Represents the current Data Value within the containing Category or Details.
{PercentageDetail}
: Represents the percentage share of the current Data Value among all values within the same Details.
{PercentageCategory}
: Represents the percentage share of the current Data Value among all values within the same Category.
{categoryField.name}
: Represents the field name bound to the Category Encoding.
{categoryField.value}
: Represents the current Category Encoding value.
{detailFields.name}
: Represents the field name bound to the Details Encoding.
{detailFields.value}
: Represents the current Details Encoding value.
{colorField.name}
: Represents the field name bound to the Color Encoding.
{colorField.value}
: Represents the current Color Encoding value.
These values can be combined and formatted using the interpolation syntax and supported format strings that are also used for the TextBox Report Item.
For example, the plot in the Radar Area Plot with Single Value Demo uses an advanced tooltip configuration:
The Text Encoding
contains the SalesQuantity
element that displays the number of sold items:
Aggregate
= Avg
Value
= {RottenTomatoesRating}
Target
= Tooltip
TemplateKey
= AvgRating
The Tooltip Template
is configured with the following expression:
{categoryField.value}
Average Budget: {valueField.value:C2}
Average Rating: {AvgRating:N2}
A subset of text properties in the Label Text
section and the line properties in the Label Border
section allow you to set up the corresponding visual parameters of the plot labels.
The Label Position
and an optional Offset
in pixels determine the location of labels relative to a parent data point symbol:
Inside
- inside the area filled with color
Outside
- outside of the area filled with color
Center
- near the data point
Auto
- equals to Outside
The Overlapping Labels
property indicates the handling of overlapping labels. Possible values are:
Auto
- hides some labels to prevent the overlapping
Show
- shows all labels even if the overlapping persists
The line properties in the Label Line
section allows you to add the connecting lines between labels and their parent data points. The Label Line Position
determines the connection point of a label's bounding box and the line:
Auto
- selected automatically
Center
- on the center of the bounding box side
This group of properties determine the Interactive Action when a report reader clicks inside a filled area. You can use bound field references to pass parameters in a drill-through report or configure a dynamic bookmark or URL. The field value is evaluated in the scope of the current detail. Visit the Drill-Through Reports Walkthrough for more information. It explains how to set up the drill-through column plot, but the same technique applies to a radar area plot.
