Plot multiple 2D Curves in 3D

[stc]

Hello,

i want to plot 3 different 2D curves in a 3D coordinate system, so lets say 3 simple sine functions. One in x and y direction, one in x and z direction and one y and z direction.
My Code already looks like:

ax = plt.figure().add_subplot(projection='3d')

# Plot a sin curve using the x and y axes.
x = np.linspace(0, 1, 100)
y = np.sin(x * 2 * np.pi) / 2 + 0.5
ax.plot(x, y, zs=0, zdir='z', label='curve in (x, y)')

y = np.linspace(0, 1, 100)
z = np.sin(x * 2 * np.pi) / 2 + 0.5
ax.plot(xs=0,ys=y,xz=z, zdir='z', label='curve in (y, x)')

# Make legend, set axes limits and labels
ax.legend()
ax.set_xlim(0, 1)
ax.set_ylim(0, 1)
ax.set_zlim(0, 1)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

But it throws an Error:

Error:
x and y must have same first dimension, but have shapes (1,) and (100,)

With only one function in x and y direction it works just fine.

Can someone help me with this? Thank you in advance,

Maxi

at minimum, missing imports, definition of plt
please, At least supply minimum snippit

[stc]

Okay so snippit is:

import numpy as np
import matplotlib.pyplot as plt

ax = plt.figure().add_subplot(projection='3d')

# Plot a sin curve using the x and y axes.
x = np.linspace(-1, 1, 100)
y = x**2
ax.plot(x, y, zs=0, zdir='z', label='curve in (x, y)')
x = np.linspace(-1, 1, 100)
y = x**2+2
ax.plot(x, y, zs=0, zdir='z', label='curve in (x, y)')
# Make legend, set axes limits and labels
ax.legend()
ax.set_xlim(-1, 1)
ax.set_ylim(-1, 1)
ax.set_zlim(-1, 1)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# Customize the view angle so it's easier to see that the scatter points lie
# on the plane y=0

plt.show()

Hope it helps

It doesn't fail for me, but axis is off on one plot

Yes it works in x and y direction, but i also want to plot the function for example in y and z direction. If you try this it will fail

but i also want to plot the function for example in y and z direction

Try this.

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Plot a sin curve using the y and z axes.
y = np.linspace(-1, 1, 100)
z = y**2
ax.plot([0]*len(y), y, z, label='curve in (y, z)')

y = np.linspace(-1, 1, 100)
z = y**2 + 2
ax.plot([0]*len(y), y, z, label='curve in (y, z)')

# Make legend, set axes limits and labels
ax.legend()
ax.set_xlim(-1, 1)
ax.set_ylim(-1, 1)
ax.set_zlim(-1, 3)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

plt.show()
