How can i generate 3 random points within a 2x2m grid?

Hello, i need to generate 3 points that are at random positions within a square boundary which is of 2x2m. I want these 3 points (wires) to also have random current values. I tried doing x=rand(1,3)*2 and y=rand(1,3)*2 but i need the graph to have 0 at the center and go from 1 to -1 on each axis. how can i do this?

I think you were on the right lines but you need to subtract one from your x and y:
x=rand(1,3)*2-1;
y=rand(1,3)*2-1;
That'll put all of your values in the range -1 to 1.

Apologies, I don't think I understand the question.
Can't you just generate another variable using rand as you did before. As previously, this will generate random numbers in the range 0-1 so you can always multiply these by whatever you want to get them in the correct range for your current.
If the question is more related to the plotting the you could use plot3 which would allow you to get your current as the value on the z-axis?
