What is considered an upward trend in GPA?

[amygdalaHPC]

During my first three years of uni i experienced a lot of hardships and unfortunate situations that led to a terrible depression i ended up being hospitalized a few times and my gpa was considerably low. I preserved though and ended up with a 4.0 in my last year. I know u of c look at overall trends in gpa but i dont really know what that means? would the following be an upward trend

1 year: 2.7

2nd year: 2.3 (most difficult year personally)

3rd year: 3.1

4th year: 3.7

5th: 4.0 (the only year i took 10 courses)
