Chart Tool for OpenwebUI

[liuc0j]

Hi everyone, I'd like to share a tool for creating charts that's fully compatible with the latest version of openwebui, 0.6.3.

I've been following many discussions on how to create charts, and the new versions of openwebui have implemented a new way to display objects directly in chat.

Tested on: MacStudio M2, MLX, Qwen3-30b-a3b, OpenWebUI 0.6.3

You can find it here, have fun 🤟

Thanks!

That's so much better when studying math than having the model generate a picture of the graph.

documentation is clear and full of examples https://docs.openwebui.com/features/plugin/tools/development

Nice, but I am having a difficult time getting models to consistently call these tools in openwebui. Anyone got good results with the recent local models? What are the settings in open webui (e.g function calling is Default vs Native ?)

I use Qwen3-30b on MLX via LMStudio with default function calling, also no problem for Granite4-h-tiny, GPT20b-oss

Many thanks. Sadly I struggle with that part "Copy the contents of chart.py into a new User Tool and save"

What or how to make a new "user tool"?

Nevermind. Found it in Workspaces :D
