Diagram settings overview

Diagram settings exist at three levels, and they resolve in a fixed order. Almost every confusing settings question is really a question about which level is deciding.

The rule is simple: the macro wins if it has an opinion, then the space, then the site.


#When you would change this

  • Before changing anything, so you change it in the right place.

  • When a setting appears to have no effect.

  • Rolling a standard out across a site rather than page by page.


#What you can set

Setting

What it does

Site settings

Which languages exist, shape libraries, templates, AI, egress, renderer.

Space settings

Rendering defaults for every diagram in a space: display mode, dark mode, titles.

Macro settings

One diagram, overriding the space where it chooses to.

#A few things that catch people out

  • Most macro settings default to inherit, which means "use the space value". That is what makes space defaults useful.

  • Turning a language off site-wide hides it from the picker but does not delete existing diagrams.

  • Site settings need Confluence administrator rights; space settings need space admin.



Set it once, in the right place.
