As far as I understand the graph shows an anomaly, so plus or minus vs a baseline, plus it's a calculated value based on temperature profile, density, etc.
More info here:

But now that you ask I'm not positive (since it doesn't actually say anomaly) that I understand it correctly. I'll check into it further.

I know one posted earlier shows a temperature increase; but the flat line of the early 20th century has one notch per degree, then after 1970 1 notch shows .2 degrees or something. Meaning the graph shows a spike; but the spike isn't to scale.

Agreed graphs can be easy to mess with to over/understate or otherwise misrepresent.
