Seems a rather glaring omission—as a software engineer in NYC, roughly 55% of my total annual compensation comes in the form of a cash bonus.
Since total compensation tends to vary more significantly than base salary, I would continue showing the salary-only graph by default, with an option to toggle total compensation as a second series.
Whoops, brain fart: that should have been 45%. But yes, I work in finance.
It's definitely not unheard of for bonuses of top engineers to reach multiples of their base salary. I'm not aware of compensation being that lopsided where I work, but it purportedly happens at places like Two Sigma.
I'm in a similar situation (~55% of comp is bonus) which is in finance, but most FAANG devs will see something similar, especially as you go more senior, although with an emphasis on equity rather than bonus.
