Use Radar Charts for Data Analysis
A dynamic and effective tool for data analysis and presentation.
Radar charts are very useful when comparing performance/measurement results, analyzing statistics, etc. from different sources. Use advanced radar chart software to draw radar charts and present data analysis visually.
Introduction to Radar Chart
Radar chart is a frequently used method for comprehensive evaluation, particularly useful for holistic and overall assessment through multivariate data. Its advantages lie in vivid visualization and ease of use. Through comparison and analysis, people can figure out their current situation: improving or falling behind. For those time-crunched managers, they can understand the situation at a glance. Generally speaking, there are 3 types of results in data analysis through Radar charts.
Benefits of Radar Charts for Data Analysis
- Vivid and visual description.
- Realization of dynamic analysis.
- Scientific depiction of industrial development track.
- Effective mastery of dynamic data for relevant department.
- Easy application and promotion, making the assessment concise, intuitive and fast, which will encourage people to pursue progress and excellence.
Data Analysis through Radar Chart: Example
For example, we can compare students' test scores with the average score on subjects such as math, computer science, and biology. A radar chart has multiple axes along which data can be plotted. Each axis is a category. The data is shown as points on the axis. The points belonging to one data series can be joined or area so enclosed is filled. A point closer to the center on an axis indicates a lower value and vice versa. In some applications, low values may be more desirable than high values, e.g. price/earning, price/sales, price/book of stocks.
From the above radar chart example, we can figure out the following information:
- Class 1 is excellent in computer science and didn't do well in Chemistry scoring only 68 points, the lowest among all subjects.
- Lucy excels in study with all subjects above the average.
- Tom should pay more attention to study since most of his scores are below the average. His strength is computer science in which he scores high and much higher than average.
