Phew, I figured it out!
For a while now, one of our Dashboard graphs started displaying information in “hundreds”. For example, “223″ would be rounded to “2″.

That’s fine when you’re working with thousands, but not great for hundreds.
I searched high and low for a way to fix this, and eventually found it in the Dashboard Edit Component screen — that’s the one one after you Edit the Dashboard and then Edit the individual component.

For some reason, the Auto setting decided to flip to Hundreds, so I just changed it to Whole Units.

The result… Happy users!
The Bottom Line
- Some settings can be hard to find
- You’ll probably forget to set this on initial creation of a Dashboard when there isn’t much data, so make a habit of setting it to Whole Units upon creation
