Hi, I am looking to create a line graph for a binary variable 'PERFORMANCE' (students with good honours vs not with good honours), across students with different backgrounds BACKGROUND (another binary variable) across years (YEARS). I would like my performance variable to show percentages of those who had good honours. The objective is to see how performance changes for these two group of students over years. I know it may be simple but I am stuck on it for sometimes. Thanks in advance.
