Display exact proportions on every slice so your audience can read the data at a glance.
Input the actual numeric values for each category — for example, the number of survey responses. You do not need to calculate percentages yourself; the chart tool will convert raw values to percentages automatically.
Percentages print on every slice by default in our editor. To change it, open Title & Text and set Labels on Slices to Percentage, Value and percentage, or Name and percentage. Each figure is calculated from the total of all values.
Labels sit inside each slice. When a slice is too thin for its text, the editor leaves that label off rather than overlap its neighbors, so keep the legend on or group tiny categories into Other.
Set the number of decimal places — one decimal is usually sufficient (e.g., 23.1%). For clean visuals, round to whole numbers when the audience does not need high precision.
After formatting, confirm that the displayed percentages add up to 100% (or very close due to rounding). If the total is off, adjust rounding rules or use one more decimal place.
