Radar Chart

Radar Chart is a type of chart that represents multidimensional data, consisting of coordinate axes, points, lines, and polygons.

Radar charts map data quantities from multiple dimensions to coordinate axes, where each dimension of data corresponds to a coordinate axis. These axes are arranged radially at equal intervals and have the same scale. Connecting the data points on each axis forms a polygon, which ultimately reflects the weight of relevant variables and is particularly suitable for displaying various performance indicator data.

Advantages: Radar charts can intuitively display multidimensional datasets, showing which variables have similar values, whether there are outliers between variables, and are suitable for viewing which variables have higher or lower scores in the dataset. They can well demonstrate performance and advantages, especially suitable for displaying multiple key features of a dataset or comparing multiple key features of a dataset with standard values. They are generally suitable for comparing the values of multiple data points across multiple dimensions.

Disadvantages: Radar charts are not suitable for data with too many categories, as they can cause too much deformation and make the overall graph too confusing. Especially in the case of polygons with color fills, the upper layer will obscure the lower layer polygons, and if there are too many variables, readability will also decrease.

Settings

Data Settings

Setting Item	Description
Data Source	Select the data source for the radar chart. Multiple data sources can be added in the Data Source menu to implement multi-chart overlay
Name Field	Select the field returned by the data source, which is used to display the name of the radar chart labels, usually displayed in combination with the Tooltip Display menu.
Value Field	Select the field as the source of each indicator data value in the radar chart. Note that it should be consistent with the indicator order in the Radar menu, otherwise it will lead to cross errors in data matching.

Chart Settings

Setting Item	Description
Radar	Select the radar coordinate axis in the Radar menu, and the radar chart will display indicator data on this coordinate
Color Allocation Type	Configure the color effect of graphics in the radar chart, options: Allocate colors from the palette by chart, Allocate colors from the palette by data item. When multiple charts are aggregated, you can choose to allocate by chart; for a single chart, you can choose to allocate by data item. The specific color values can be adjusted in the palette of the Style menu.
Graphic Style	Select the graphic style of the radar chart. Options: Hollow Circle, Dot, Rectangle, Rounded Rectangle, Triangle, Diamond, Needle, Arrow, None
Graphic Size	Configure the size of graphics in the radar chart
Graphic Rotation Angle	Configure the rotation angle of graphics in the radar chart

Label Settings

Setting Item	Description

Events

Setting Item	Description
Not Clickable	After enabling, all label data in the chart cannot be clicked; after disabling, you can set the corresponding data click interaction event
Call Automation on Click	You can implement related data label click interaction events by selecting the corresponding automation, such as opening the corresponding data form details or opening other web links after clicking
Call Automation on Double Click	The function is the same as click call, but the interaction is triggered by double click instead of single click. Click and double click events can be set simultaneously
