Cross Reference is an open-source cross-referencing add-on for Google Docs. It automatically numbers elements such as figures and updates and formats in-text references to them.
Create a label for a figure by writing the word ‘figure’ in the caption and then adding a hyperlink to that word with the URL #figur_YOURCHOSENNAME. Refer to this figure in your text by writing ‘figure’ again and adding a hyperlink with #fig_YOURCHOSENNAME. Update the document via Add-ons → Cross Reference → Update document.
