No, it doesn't. That's a chart of the average annual interest rate of 30 year mortgages, not the share of mortgages that are 30 year mortgages.

That is a chart of the interest rate of 30 year fixed rate mortgages in the United States.

What does that have to do with the ratio of fixed rate to adjustable rate mortgages?

That's the mortgage interest rate, not the percentage of 30-year fixed rate mortgages vs. ARM.
