How to read Radar Chart
If we see the above chart we observed there are 5 students which are on every side of the polygon(pentagon). Apart from this we also find the score of 4 subjects is available and it is visualized by the different colors of lines. Also, there is a scale from the center point to the highest point.
From this graph, it is easily interpreted that Jiya has the highest score in English. Also, we can see Shin got the highest in Chemistry.
|1||Excellent in comparing different variable easily||Area of the polygon varies with variation in the arrangement of axes.|
|2||Takes less space as compared to others||Radar charts are harder to plot.|
|3||Circles inside the chart can be used as grid lines for measurement.||These charts are limited to a certain type of data.|
|4||Radar charts are good at showing variation in data||Too many variable crowds up the chart and makes it unreadable.|
