Help writing code for 3D vector plots

[Gottlieb David]

Goal:To write a program for displaying and analyzing vectors in 3D utilizing SAGE.

Progress to date-The attached figure shows the code and product graphic with 3 orthogonal basis vectors created in the SAGE cellular system. So far so good but I'm having problems going forward.

I want to control the length of each axis independently and have tried all the established codes I could find;none work. The second problem is line thickness. I can control it in SAGE cellular but it doesn't work in the SAGE MATH ONLINE with a regular SAGE worksheet. The lines are thin and hard to see. 

Any suggestions?

What I know for sure is : you better had posted your support issue on the "new" google goup, sage-cell.

And because that's annoying (at least for me) :

- don't use "SAGE" word (it's acronym name of a company not related to sagemath),

- replace "SAGE online" with "sagemath cloud" (with same meaning than "Sagemath Online") or "sagemath cell" or "sagemath" : there are three different websites (the last one is the older one and have mirror websites in various releases) .. they are working differently even if they have common core code,

- please, replace "cellular" with "cell" in your sentences ... I am not english fluent but "cellular" is mostly used for phones and "cell" is the right word for part of a worksheet  (my POV)

- don't forget to add : exact URLs,  your browser (name and release,..), release of sagemath and for the code : either you write it in post (not in attached PDF) or for a cloud worksheet, you make simple worksheet  "public" and you post the link
