Frequently Asked Questions

How can I make my chart look like X?

QuickChart uses the popular open-source Chart.js library, so you can use all Chart.js documentation and Chart.js-related search terms to answer questions on how to customize your chart. If you're stuck, feel free to email us.

Do I need a license to use QuickChart?

Charts generated by QuickChart are public domain. You don't need a license or any permission to use or distribute images produced by this site.

If you'd like to fork the code, keep in mind this project is licensed under GPLv3 and you should make your code public and retain the copyright notice. If you'd like to license QuickChart privately or commercially, or if you'd like help setting up a private instance, please get in touch.

Is this a suitable replacement for Google Image Charts?

This service is a replacement for the Google Image Charts API, which turned off on March 14, 2019.

Chart.js doesn't match exactly with the Google Image Charts API - it is based on a more flexible, general-purpose charting specification. Both Chart.js and QuickChart have strong open-source communities. QuickChart also has a drop-in replacement for Google Image Charts documented here.

We encourage developers to choose a fully open-source solution over proprietary services in order to mitigate risk and future-proof their choice of API.
