Make a graph plz help

I’m sorry but, I don’t get what you exactly mean. all the coordinate systems that I found on the web this week, weren’t the ones I was looking for

I need to make a x and y axis both until the number 1000. And the numbers I get from the arduino need to go in the graph.

And every second I get a new set of numbers, so the point in the graph need also to change to the other place where x and y axis cross eachother.

I hope you can help me with this, because this is what the assignment says
