Inconsistent visualization rendering (chart_type mismatch)

Posted on by CU15090955-0

I've created a fabric data agent and published it. I've connected it to Copilot Studio. However, Copilot Studio intermittently displays/generates the wrong visualization type even though the Fabric Data Agent has returned the correct chart_type (e.g., the agent returns "bar" but Copilot Studio renders "line", and sometimes Copilot Studio auto-generates a chart even though the user did not request a visualization). Why is this happening? What should I do?

Inconsistent visualization rendering (chart_type mismatch)

hello

Probably you have the internal LLM wich is trying to rewrite the content, could you try to disable the folowing :

- System topics : Conversationnal topics (it will work in the dev screen , to go in publish you will have few other topic to disable wich are linked, but to test it's an easy first step)

- General knowledge : sometime have internal skill wich interfer

- public web (but you probably already remove it

and last bu not least

in the agent connexion i tend to remove the "send the all context/prompt to sub agent" , it's a checkbox in the detail screen of sub agent : i have more problem than it solve with this option, it often generate a lot of sub exchange wich modify the answer

PS : did you activate the trace topics and activity cards ? sometime with sub agent you have some topics wich are triggered in the main one

PS : I had many problem with sub agent with GPT 5 reasoning (was ok with GPT 5 auto)

I hope it help a little :)
