Hello,
I need to draw phasors (lines-vectors) for AC circuit analysis.
- Line from origin to a point.
- Line from a point to another
The magnitude and the angle or Real and Imaginary parts are known.

Is there any related example?

Thank you,
Basile

Thank you Jean.
Any way to use different colour for some segments?
Put an arrow or a circle at the end?
Have a text to identify each segment?

You can use X-Y Plot Region for this.

Hello Basile,
You should be able to build your circuit with the attached.
Make something, attach and we will add text if you can't.
Cheers ... Jean

Hello, Basile
On that one you can do a bit more.
Too much may be too much, isn't ?

Hello Jean and Uni,

Why the Lv is not defined?
I express the matrices as function.
And then the vectors evaluate!
What are the red squares to the right?

It looks that this approach of drawing vectors is a begging.
I shall work on it.

Thank you,

Red square in the scroll bar points at the errors in the document.

More elegant arrows proposed.

Hi Jean,
The arrows fail when the length of the vector changes.
I have tried as a percentage of length but does not look nice.
Scaling the vectors to always be one but will loose real valuesSMath-1.PNG.
Any good idea?

Is there a way to auto-scale the 2D plot or X-Y plot?
One of the vectors is out of the visual plane.

Thanks,
Basile

I do not know how to do it better. The arrow should look good in different scales and in its own size.

One of the vectors is out of the visual plane.

None of the quick plot or X_Y plot can be made X, Y directions scalable
similar to Mathcad 11 ... to me: useless.
From an original X_Y plot creation, stretch by handles respect aspect ratio.
If you modify the X, Y directions [max/min], apply close enough HL, HW ratio.

With both arrow heads, based on Jean's method.
Thank you Jean.

Hi,
Why I am getting errors when load your file?
The latest Stable: SMath Studio 0.99.7030 (01 April 2019)
SMath-3.PNGSMath-4.PNG
At the end I am able to open the file.
I do the same with two arrows 2π apart, but yours is more elegant.
