Polar Chart

The Polar Chart displays data points on a radial axis using polar coordinates, and is effective for comparing the distribution of one or more series of data points.

Data

The Data properties group includes properties for Building Chart Datasets that are common to most charts. The following properties are specific to the Polar Chart.

The Polar Chart allows data points to be precisely placed in the chart using the Category field of the Source Data. The Category field in this case is an Integer, and indicates the absolute angular position of each point in degrees.

For automatic distribution of categories around the circumference of a circular chart, consider using a Spider Chart.

Source Data

The source data table used for building custom-data-based charts. The Value field of chart is interpreted as the radius, and Category is interpreted as the angle (theta) in degrees.

Source Data Bindings

A set of expressions used to retrieve data from the records of the Source Data table and build the chart dataset. This property only applies to charts based on custom data.

Variable Name:

dataBindings

Records:

Record Format:

Field Name

Field Type

Field Description

series

String

Expression to define the Series of the chart dataset.

value

String

Expression to define the Value of the chart dataset.

category

String

Expression to define the Category of the chart dataset.

All fields of the Source Data Bindings table have the following Resolution Environment:

Default Context

Specified by the Context setting.

Default Data Table

Value specified by the Source Data table.

Default Row

0 (or dynamic if series propagation is enabled)

Environment Variables

Standard variables only.

Radial Axis

The Radial Axis extends outward from the center of the polar chart, representing the distance or magnitude of data points from the center. The properties defining the styling of the labels and tick marks of the Radial Axis are the same as those of the X Axis Properties.

Angular Axis

The Angular Axis, also known as the azimuthal or circular axis, is the circular line or set of lines that divide the polar chart into sections of concentric circles. The properties defining the styling of the labels and tick marks of the Angular Axis are the same as those of the Y Axis Properties.
