The given line chart compares the number of first-grade students between two different schools over a period of 10 years ending in 2019. In general, these figures followed 2 distinct trends throughout the featured timeframe.
As can be seen clearly from the chart, starting from 20 in 2010, the number of school 1 increased dramatically to 44 in the next 4 years. The next year witnessed a fluctuation in this figure for school 1 which decreased sharply and hit a low point at 34 in 2016. From 2016 to 2017, there was a significant rise in this figure reaching the peak at 50 in 2017 and falling slightly at 44 then. The last year remained roughly stable at 44 which was twice the starting point.
In contrast, standing at a much higher 32, in the first 3 years this figure for School 2 grew gradually which was opposite to the rapid fluctuation of its counterpart. Between 2013 and 2016, while the number of students in School 2 fell rapidly, that of School 2 fluctuated. However, in 2016, both figures hit a low point, this figure for School 2 was lower than that. The last 4 years witnessed a dramatic growth in this figure of school 2 at 50 which was higher than the finishing point of the school 1 number.
