creating a 2d plan graphic and projecting points in it

Hello;
I want to create a 2 D plan with (123 values) for axis1 and 7 values for axis 2.
I then want to make a projection of points with their coordinates in that plan!
is that possible and how to proceed?

In fact the 123 values range from: (minus) -1,50156 to 0,61068 and I need to enter them as graduation for the X axis (axis 1) and the other 7 values (0,458333333 0,609 0,6123 0,63 0,72 1 1) I need them to form a graduation for axis 2.
then I have points with coordinates (x,y) that I want to project on this 2D plan.

Thanks

It may well be possible but I would image I like others have no real idea what you want.

Read your post again but this time try and imagine you know nothing about the background to the question. Does it still make sense?
