I found the difference: the working cells were using viewer='threejs'. When I change the other to threejs it works, although I don't like the plot as much. Is there a way with the threejs viewer to get an orthogonal projection instead of perspective? To repeat from my initial post: I'm sure tha

In my calculus book I have a number of sagecells. One of them has started throwing an error involving CORS. Follow this link: https://www.whitman.edu/mathematics/calculus_online/section13.01.html and go to the exercise section, click evaluate on the sagecell. When I do this, I get Error conne

Thanks, Tom. So far as I can tell, your examples use "arrowsize" and "width" to control the arrows. But so far as I can tell, those parameters have no effect on 3d plots -- yours are all 2d. Am I missing something? I'm using the SageMathCell server to test; not sure if that affects the answ

You can adjust the arrowheads. Look at http://faculty.sfasu.edu/judsontw/ode/html-20190111/firstlook03.html for some examples. On Sunday, January 27, 2019 at 10:11:47 AM UTC-6, Tevian Dray wrote: > > Can the formatting of arrows in 3d field plots be adjusted? > > I'm trying to make rotatable,

[sage-support] arrows in 3d field plots

2019-01-27 Thread Tevian Dray
Can the formatting of arrows in 3d field plots be adjusted? I'm trying to make rotatable, 3d versions of 2d field plots. I can get most of what I want with, say: xy=plot_vector_field3d((x,y,0),(x,-1,1),(y,-1,1),(z,-1,1),colors='black') show(xy,orientation=(0,0,0,0)) but I'd really like the
