How do I centre a diagram in Confluence Cloud

I've drawn a basic vertical flowchart using the plugin for Confluence Cloud but no matter where I position the diagram on the page in, it appears resolutely stuck to the left margin when I save and exit to Confluence.

In Confluence itself, the macro takes up the whole column width and doesn't offer an alignment button when you click on the macro diagram, only column width, edit or delete.

How do I centre the flowchart in the column on the Confluence page?

Our engineers have been working on this and added the possibility to “Center“ as shown in the attached image. So please open the diagram in editor, tick “Center“ and click Save&Exit. Does it help?






I am having the same issue. How to go to the viewer settings for an drawing?


open a Confluence page where diagram was created, hover a diagram, click Edit diagram pencil (top left) and you should be able to see Viewer Settings.

If you don't see it, repeat all the steps in a different browser and Incognito mode. Also, clear the cache. Incognito mode is great for testing cause it is cache and extension free (cache and extensions can cause some problems sometimes)

If nothing helps, tell me version you are using please (can be seen under Settings > Manage apps > expand

As a work around, I have used a rectangle box flattened and extended along the bottom horizon to title the diagram. With the line color same as the background is keeps the diagram centered. 

Hi @Marija Radovic - Center function only works when toolbar option is set to 'Top'. Otherwise (hidden, embedded), the center function will not have any effects when the diagram is rendered in the confluence page.

Also, there are layout bugs within Mozilla Firefox 88.0.1 version (other versions not checked, latest Google Chrome is fine), e.g.: Right border of widget not displayed, hover inconsistencies, settings box not opening options or not displaiyng properly when opened within the widget in confluence view mode.

Do you think the hidden & center bug will be fixed soon?


for the first "top"report could you tell me browser version and operating system you are using, please? 

For the second, is it possible to send a video showing all the issues you reported so we could be sure we understand them completely?



Hi @Marija Radovic ,

yeah sure!

Browser: Mozilla Firefox, 88.0.1 (64-Bit)

OS: macOS Big Sur, Version 11.3.1 (20E241)

Where should I send you the video?

Best, M

Great :)

You can attach it here or if you have some sensitive data, submit all the details + video here:



Hi Mate,

Sorry for the late reply. I created the issue and assigned our engineer so he could take a closer look. 

Please track it here:

Kind regards,


Does not see the center option aswell, using 9.4.8, any suggestions?


If you are using for Confluence Server, click Edit page pen (top right) and you should be able to see alignment options as shown in the image bellow (marked yellow) 

Does this help? 

Kind regards,
