Thread: Plotting 3 variables

Hello,

Whats the technique for plotting 3 variables such as (7,-4,1)?

I was trying to figure out how to draw a 3d box.

Thanks,

Well, the problem is not really "plotting 3 variables". It is "plotting three dimensions on two dimensional paper".

I would recommend drawing two orthogonal axes representing x and z and drawing the y- axis at an angle "into the paper. Then you are going to have to pretty much "eyeball" the point- 7 spaces on the x-axis, 4 down on the z-axis and 1 "into the paper" on the y-axis.

Thanks! do you know a free online 3d graphing calculator I can use?
