Radar Chart
Overview
A Radar Chart is a two-dimensional chart type that displays one or more groups of values on radial axes. Multiple variables are used to compare these values. Radar Charts are often used to compare several items across multiple criteria simultaneously.

Creating a Radar Chart
Creating a Radar Chart requires categories and two numerical value sets for the categories.
For example, the query:
source saf_cs_web_indexes
| stats count as count_by_ip by source.ip
| sort -count_by_ip
| eventstats sum(count_by_ip) as total_count
| head 10
| eval percent = round((count_by_ip / total_count * 100), 2)
| table source.ip, count_by_ip, percent
| rename source.ip as ip_источника, count_by_ip as "Number of requests from source", percent as "Percentage of total number of requests"
will return the following result:
After that, by switching to the Visualization tab, you can select the Radar visualization type and add it to the desired dashboard by clicking the Add to Dashboard button.
