hello. can you tell me how do you categorized each line's symbols (the colors) if the data is from an online database? each color represents each value. the database includes each value from each segments of the line. i don't want to categorize them manually. i've been looking for answeres but i can't seem to find some. i hope you can help. thank you so much.
