A Radar Area Series, also called a Spider Area, shows the magnitude of various datasets within shared categories, making it easier to gauge area-based trends.
Simple Radar Area
To create a Radar Area Series, use the radar-area series type.
series: [
{ type: 'radar-area', angleKey: 'department', radiusKey: 'quality', radiusName: `Quality` },
{ type: 'radar-area', , angleKey: 'department', radiusKey: 'efficiency', radiusName: `Efficiency` },
],
In this configuration:
angleKeyis set to 'department', which is the shared category for the Angle Axis.radiusKeyspecifies the numerical datasets, 'quality' and 'efficiency', for the Radius Axis.radiusNamelabels each series, such as "Quality" and "Efficiency".
Customisation
Axis Shape
For Polar Axes, there are two shape options:
polygon: Connected with straight lines (default).circle: Composed of concentric circles.
To switch to the circle shape, use the following axes configuration:
axes: [
{ type: 'angle-category', shape: 'circle' },
{ type: 'radius-number', shape: 'circle' },
],
Axis Label Orientation
To change Angle Axis Label orientation, use the label.orientation property with these options:
fixed: Labels have fixed orientation (default).parallel: Labels align parallel to the axis.perpendicular: Labels align perpendicular to the axis.
The following configuration changes the orientation of the Axis Labels to parallel :
axes: [
{
type: 'angle-category',
label: {
orientation: 'parallel',
},
},
{ type: 'radius-number' },
],
Radius Axis Position
Customise the Radius Axis Line position via positionAngle and Axis Label rotation using label.rotation:
axes: [
{ type: 'angle-category' },
{
type: 'radius-number',
positionAngle: 72,
label: {
rotation: -72,
},
},
],
API Reference
Properties available on the AgRadarAreaSeriesOptions interface.
Configuration for marker and series highlighting when a series or legend item is hovered over.
Primary identifier for the series. This is provided as seriesId in user callbacks to differentiate multiple series. Auto-generated ids are subject to future change without warning, if your callbacks need to vary behaviour by series please supply your own unique id value.
The data to use when rendering the series. If this is not supplied, data must be set on the chart instead.
A human-readable description of the angle values. If supplied, this will be passed to the tooltip renderer as one of the parameters.
Properties available on the AgAngleCategoryAxisOptions interface.
This property is for grouped polar series plotted on a angle category axis.
It is a proportion between 0 and 1 which determines the size of the gap between the items within a single group along the angle axis.
This property is for grouped polar series plotted on a angle category axis.
It is a proportion between 0 and 1 which determines the size of the gap between the groups of items along the angle axis.
Properties available on the AgRadiusNumberAxisOptions interface.
The ratio of the inner radius of the axis as a proportion of the overall radius.
Used to create an inner circle.
