The line chart demonstrates the changes in annual wages of certain professionals over the 15 years. Apparently, salaries of all experts is raised over the whole period.
In 2001, data scientists’ salaries’ index was 75, in the following 6 years this number doubled and in 2011 it reached its peak, showing nearly 200. Starting point of computer engineers’ yearly income was approximately 35, and it slightly increased until 80 in 2007, and by 2011 it stayed the same. However, last point of it is 170, so it boosted till 2015. Both of these lines have never been decreased, only if it wasn’t frozen in one place.
Unlike two previous lines, mechanical engineers’ index dropped from 80 to 20, and lasted in 20 from 2005 to 2009. However it reached 90, in 2015. Civil engineers and Software engineers were on 50 and 40, respectively, and didn’t make any changes until 2011, being parallel to each other. Between 2011 and 2013, software engineers’ wage sky-rockets until it reaches 225. However measure of civil specialists endured, and only in 2014 it grew a bit, indicating exactly 75.
