Frequently Asked Questions

What's the difference between a pie chart and a doughnut chart?

A doughnut chart is essentially a pie chart with a hole in the center. The main difference is the inner radius - pie charts have no center hole (0% inner radius), while doughnut charts have a hollow center. Doughnut charts are often preferred for modern dashboards and presentations due to their cleaner, more contemporary appearance.

Can I adjust the size of the center hole?

Yes! You can control the inner radius from 0% (which creates a pie chart) to 90% (which creates a very thin ring). The default is 50%, which provides a good balance between readability and modern appearance. Adjust the inner radius based on your design needs and the amount of data you're displaying.

Can I download the doughnut chart as an image?

Absolutely! Click the "Download PNG" button to save your doughnut chart as a high-quality PNG image. The downloaded file will be named based on your chart title and is perfect for presentations, reports, and documents.

How do I embed the chart in my website?

Click "Generate Embed Code" to get HTML code that you can copy and paste into your website. The embed code includes Chart.js library and will create an interactive doughnut chart on your page. The embedded chart will respect all your current settings including inner radius, colors, and display options.

What format should I use for entering data?

Enter each data point on a new line using the format "Label:Value". For example: "Desktop:45" on one line, "Mobile:35" on the next line, and "Tablet:20" on the third line. The tool will automatically parse your data and create the chart segments.

Can I show labels inside the chart segments?

Yes! Check the "Show labels inside chart segments" option to display labels and percentages directly inside each segment. When this option is enabled, the legend will be automatically hidden to avoid duplication. This is great for creating self-contained charts that don't require external legends.

What's the percentage mode feature?

The percentage mode converts your raw values to percentages, normalizing them to 100%. This is useful when you want to show proportional data rather than absolute values. For example, if you enter "Desktop:45, Mobile:35, Tablet:20", percentage mode will display "Desktop:45%, Mobile:35%, Tablet:20%" instead of the raw numbers.

Do I need to create an account to use this tool?

No account required! Our doughnut chart generator is completely free to use without any registration. Simply enter your data, customize your chart, and download or embed it instantly.
