from sage.plot.plot3d.shapes2 import Line
Line([(i*math.sin(i), i*math.cos(i), i/3) for i in range(30)], arrow_head=True)
The result is a long error message ending with "TypeError: 0 is not JSON serializable". Am I doing something wrong?Jeremy MartinWed, 23 Sep 2015 20:49:15 +0200https://ask.sagemath.org/question/29546/
