# A simple vector.

## A simple vector.

(OP)
I need to draw a simple 3D vector to a point in space. How do I do it? (using MathCad 11.2)

I have data arranged in arrays based on the coordinate value(x-array, y-array, z-array) because thats the only way I can get the points in the right place or to appear at all.

For example...
-------------------------------------------------------
/ 1.995  \
point1x := | 5.235  |
\ -1.193 /

/ 2.390  \
point1y := | 5.235  |
\ -0.292 /

/ 5.548  \
point1z := | -7.681 |
\ -5.076 /

//Plot box

This plots the three points I gave coordinates for.
I want to specifically draw vectors from the origin to each point in space, and label them on the graph.

If there's a way to lock the axes @ (0,0,0) that would also be helpful.

Its a directional magnetic field from certain points about a polycyclic aromatic hydrocarbon.

The origin represents the point in space the field strength was computed from. The vectors represent the direction of the magnetic field.

Help!

### RE: A simple vector.

Here is a rudimentary Isometric representation of three vectors in the space starting at the origin of coordinates to three given points.

I am not sure if this could be done using the existing 3-D
