How to replace Google Image Charts with Open Source

Get Started

This guide describes how to replace Google Image Charts with a free, open-source replacement. QuickChart is mostly compatible with Google Image Charts and serves as a drop-in replacement.

Here are a few things you should know before getting started:

  • QuickChart is an open-source service that renders static chart images compatible with Google Image Charts. You can host your own server from source code or a Docker container, or you can use the reliable web service and not worry about hosting.
  • This page is for people looking to replace existing Google Image Charts implementations. To start from scratch with QuickChart, go to the main documentation.
  • If you're starting fresh, use the open-source Chart.js format instead of Google Image Charts format. It's more flexible, has a strong community, and will never be deprecated.

Migrating from Google Image Charts

Replace with in the URL.

For example, the URL:,5,5|10,10,10|15,15,15&chco=4d89f9,c6d9fd,00B88A&chds=0,20&chbh=a&chxs=0,000000,0,0,_&chxt=y&chm=N,000000,0,,10|N,000000,1,,10|N,000000,2,,10
