What is the best chart type for comparing data?

Bar charts are the best chart type for comparing values across categories. Use horizontal bar charts when category names are long, and vertical bar charts for time-based comparisons. ChartGen.ai's AI can automatically recommend the best chart type based on your data structure.

What chart should I use to show trends over time?

Line charts are ideal for showing trends over time and continuous data changes. Use area charts if you want to emphasize volume or cumulative totals. ChartGen.ai can create both types and will recommend the best option based on your data.

When should I use a pie chart?

Use pie charts to show part-to-whole relationships when you have 2-5 categories that sum to 100%. Avoid pie charts for more than 7 categories or when comparing similar values. ChartGen.ai will suggest alternatives like bar charts if your data isn't suitable for pie charts.
