Earlier quoted context omitted.
I can't tell if you're being serious or not.
Totally serious. I changed the graph to "relative" to show growth of the term over the period.
Let's assume that there's 10,000 total job postings in your graph. If the "rock star" trend grew from just 1 posting to just 70 postings, that would represent a 7000% growth over the period, even though "rock star" would still represent just .007 of the total market.
Growth graphs answer a very specific kind of question, and it's rarely the question that people mean to ask.
Or, put another way: click the "Absolute" link next to "Scale", under "engineer, programming, engineering, rock star Job Trends".
