Asking someone else to graph data for you to analyze is a disrespectful misunderstanding of how data analysis work.
The person graphing is doing the data analysis. They have to, at some level, to make the data presentable. If you are incapable of doing that, and your contribution is to be fully reliant on what they graph so you can look at what they make and go “huh yeah line does go up” you aren’t useful. They can tweak the data to say many things, and you wouldn’t understand it happened.
