Frequently Asked Questions
How do I create a pie chart from a spreadsheet?
Upload your file, select your category column (slice names) and value column (slice sizes), and your pie chart generates automatically.
Can I show exact percentages on the pie slices?
Yes! Toggle 'Show Data Values' in Chart Settings to display value labels directly on the chart slices.
Are there limit to how many slices I can display?
For optimal readability, pie charts work best with 3-10 categories. For larger datasets, try a bar chart.
