如何围绕列表给出的曲线绘制螺旋线？

Question

如何在list给出的橙色曲线周围绘制螺旋线？方位角、仰角和图形大小已设置为所需结果。

# Plot figure with size
figsize=(10,5)
fig = plt.figure(figsize=figsize)

# Axes 
ax = fig.gca(projection = '3d')
azimuth=90
elevation=90
ax.azim = azimuth    # y rotation (default=270)
ax.elev = elevation  # x rotation (default=0)

r = 0.1
c = 0.5
t = np.linspace(0, 5000, 100)

# parametric equation of a helix
x = r*cos(t)
y = r*sin(t)
z = c*t
ax.plot(x, y, z, zdir='z', lw=2)
ax.plot(A, B)
plt.show()

期望的结果是穿过螺旋中心的橙色曲线。

能否详细说明或在曲线中添加更多细节？
