Question 1

How to generate a chart image in Python using QuickChart?

Accepted Answer

Use the official quickchart-python library to create a chart object and generate a URL or download the image. For example, install via pip and call QuickChart() with your Chart.js configuration to get a shareable image link.

Question 2

QuickChart vs Chart.js: when should I use which?

Accepted Answer

Use QuickChart when you need static images for non-dynamic environments like emails or reports. Use Chart.js directly for interactive, client-side charts in web applications with real-time updates.

Question 3

Can QuickChart handle dynamic data for charts?

Accepted Answer

Yes, but it requires generating new URLs with updated data parameters each time, as it produces static images. For truly dynamic updates, you'd need to regenerate the image server-side or client-side via API calls.

Question 4

How to self-host QuickChart on AWS?

Accepted Answer

Deploy the Docker container to AWS services like ECS or EC2, using the provided Dockerfile. Ensure you set up proper networking and security groups to manage port exposure and sandboxing for safety.

Question 5

Is QuickChart secure for public use if I self-host it?

Accepted Answer

Not without precautions. The README warns that Chart.js configs may contain arbitrary JavaScript, so you must sandbox the instance, such as by using container isolation or reverse proxies, to prevent code injection attacks.

Question 6

What are the customization limits for QR codes in QuickChart?

Accepted Answer

QR codes support parameters like size, margin, error correction level, and color customization via URL options, but advanced features like logos or complex shapes are not natively supported without modifying the source code.
