According to the 2012 California Census, there are 10 million Mexicans in that state alone, so the chart must be of legal immigrants only: http://quickfacts.census.gov/qfd/states/06/06037.html

I have some other stats somewhere where 60-70% of illegals are Mexican, and that most Mexicans in the US are here illegally.

“As of March 2010, 11.2 million unauthorized immigrants were living in the United States”

Then see Figure 2 at

Do the math, roughly 63% of illegals are Mexican.
