iOS How to have your app make a graph based of of data in the app?

hey guys, i am making a app that i want to be able to log your weight and keep track of it, which displays in on a simple line graph

i am using a picker to log the weight, and that works fine, but i am not sure how to start making the graph? I have not a slightest clue!

THANKS!

There are some public libraries to put a graph on ur iPhone screen, from a .plist or XML or similair.
Think u need to google that

The output linked looked like a line graph to me. Can you define what you mean?

ah shoot i forgot to edit my reply I did not mean to say that im sorry, my question was to be how to make the graph only take up half of the page
i was messing with all the numbers in the code but i couldn't figure it out, also how would i have the graph use the numbers that are logged from the user?
