This plugin should be used as-is, as an unsupported example for developers.


Add automatic numbering to the shapes in your diagram with the number plugin. It will number each shape as they are added to your diagram. You can change the order by bring shapes to the front or sending them to the back - the numbering is based on their order (depth) in the diagram.

Load the number plugin


Permanently load the plugin

If you want to always use the properties plugin, add it to the plugins list so it will be loaded each time you create or edit a diagram.

  1. From the menu, select Extras > Plugins.
  2. Click Add.
  3. Select number in the drop-down list of built-in plugins, then click OK.
  4. Click Apply.

Reload your browser tab to load the plugin into the diagram editor.


Show or hide the numbering in your diagram

Click View > Number to show or hide the numbering in your diagram.


Share a diagram using the properties plugin

By default, diagrams published to URLs do not load plugins. To allow someone to see your diagram with its numbers on shapes, when you publish a diagram to a URL (File > Publish Link), add the &p=number URL parameter to the link before you share it (as highlighted in blue in the screenshot below).


Note: Plugins are not supported in draw.io for Confluence.
