Comparing Products with Polygon Charts

When comparing multiple products or services across several attributes, a polygon chart provides a far more comprehensive view than a standard bar chart or table. Each axis represents a product feature or evaluation criterion, and each product appears as a differently colored polygon, making it easy to identify which option performs best across the board.

Choosing Comparison Dimensions

Effective product comparison polygon charts use 5 to 7 dimensions that matter most to the decision-maker. For consumer electronics, typical axes include performance, battery life, build quality, display quality, price-to-value, and software ecosystem. For software products, consider ease of use, features, integrations, support quality, pricing, and scalability.

Normalizing Data for Fair Comparison

For a polygon chart to accurately compare different products, all dimensions must use the same scale. If you score each dimension from 1 to 10, ensure that a score of 10 consistently represents the best possible performance across all categories. For dimensions where lower values are better (such as price), invert the scale so that a higher score still represents a better outcome.

Reading the Results

A product whose polygon extends furthest on the most axes is generally the strongest overall performer. However, pay attention to which axes matter most for your specific use case — a product may excel overall but underperform on your most critical dimension. The visual immediacy of the polygon chart makes these trade-offs easy to communicate to stakeholders and decision-makers.
