Where is the key for the icons on the scrum board, sprint backlog, etc?

[Deleted user]

There is no key for the icons being used.

I can't say I've found a listed key anywhere, but much of Jira is hover help.  Otherwise, I search community like you all did here.

How do we know what they mean / where can we find out?

Example, I'd like to know what these (and other icons and numbers mean)

[Celena San Miguel]

If you hover over each of those icons, it shows you what it's for.  

Gray is story points (or whatever you measure by) not started

Blue is measurement in progress

Green is measurement done.

See my example below.   When you hover it shows total story points or whatever you are measuring by.  I use story points.

I am having this exact same issue. We just noticed it this morning. Our audit log indicates nothing that would cause this (just general user management). Our build info is below:
