OT: Name for vector plot

Hi all.

When one wants a graphical representation for the
vector [1,2] one draws a coordinate system and an
arrow from origo to the point (1,2).

Does this type of plot have a name?

Vector graphic?

:-)

Wasn't that a method for rendering graphics on CRTs?

I have an idea for an alternative way to visualize a vector.
I need a name in order to distinguish between the two
methods. "Vector plot" is the one name I can come up
with for the usual visualization, but it is a bit unfortunate
since the other method also plots vectors...

It's the name given to graphics that are stored as recipes (like: place
a cricle here, a dot there, draw a line from a to b), as opposed to
directly storing bit maps.

This article does mention graphics on CRTs (and calls the "X-Y
displays").

Yeah well :-).

How's about "arrow plots"? Anycase, what is your idea`?

"Phasor plot"? Don't know if that is universially accepted,
though, or is only used in EE.

I have an idea to visually represent vectors in 2D and 3D
that easily extends to N-D. I don't think it is very useful in
either 2D or 3D, but it might serve as a tool to demonstrate
that the vector concepts are valid in N-D.

When I was at college we used to call these Argand Diagrams, or Argand
Plots. Have these term fallen into disuse?

Hi Rune,

From my experience, I think it would be called simply "vector plot" or
"plot of the vector" or "plot of vectors."

I've never heard it; at least that I can remember. That was exactly
what I was looking for. 

Thanks!

It looks like my college education finally paid off ;-) But I have to admit
that it's been nearly fifty years since I've referred to this term. 

I used to wonder why it was called Argand - I thought ArgAndModulus would
have been a better description. It was a while later that I found out that
Argand was the mathematician that worked on it. Anyway, it helped me
remember the name for my exams.

It's not exactly apropos. One plots complex numbers on an Argand 
diagram, not the vectors from the origin to them. To be sure, it's a 
minor distinction.
