For example, I have the following situation:
An/The example of a password is shown in Figure 1.
a picture goes here
Figure 1 - An/The example of a password
What article should I use? Should I say "The example" or "An example"? The question is not about articles, it's more about figure captions and what I should use.
From this article I see that it may be omitted.
As you found elsewhere, your third option is to omit the article completely and just say "Example of a password". This is valid, and best-suited for formal reading.
