Chart Image from Quickchart Node not displaying in chat

Questions
1

I have successfully created a workflow that generates data charts with the relatively new Quickchart node. The node returns JSON and the resulting chart as a binary image file.

I want to use the response of this workflow in another workflow (Analytics Agent), the chart should be displayed in the chat.
But this is not working, there is just descriptive text, no chart.

I saw some examples of workflows that were created before the Quickchart Node existed. In these workflows, Quickchart was called via a Set node, the response was specified to be in markdown format.

Now, in the dedicated Quickchart node I don’t find the option to pass results in markdown.

Is it even possible to display binary image files in the chat window in n8n?
Any ideas?

You could upload the image into a publicly accessible store (e.g. GDrive, S3 or any other service allowing hotlinking) and refer it in markdown following the notation:
![image alt text](imageUrl)

Here is an image embedded into this post using the above notation:
