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

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

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()
