The circular radar chart maps the data volume of multiple dimensions of different series to the coordinate axis. These coordinate axes start at the same center point and usually end at the edge of the circumference. The points of the same group are connected by lines, and the series are distinguished by filling the line with transparent color and the area of the center of the circle. Circular radar charts are suitable for displaying performance data. Because the measurements of different dimensions of this radar chart are different, the dimensions cannot be compared. Radar chart is mainly used to evaluate the operation status of enterprises - profitability, productivity, liquidity, security and growth. The distribution of the above indicators is very similar to the shape of radar, so it is named.
