It's not a glitch. It's just FRED.

From the FRED blog I took their Bank Failures graph and added total (TCMDO) debt (red):

Thought it was odd that the red area was floating up above the horizontal axis. But whatever, it's not my graph. It's FRED.

I didn't want an area graph. Changed it to a line graph. Here's what I got:

The red line sank down and now starts below the x axis.

Weird. The numbers shouldn't change, when I change the style of the graph.
