When I save a 3d surface plot to .pdf with linewidth=0 I can still can see some white lines, which polutes my final output when seen in pdf format.
I strongly believe this is caused by antialiasing, so I tried antialiased=False, as suggested by others. It works for raster images, but the pdf image still shows these lines.
Fortunately I found a similiar question for contour here, which does:
for c in cnt.collections:
c.set_edgecolor("face")
This answer looked very promising, but for 3d plots the object Poly3DCollection has no attribute collections.
Is there any workaround for 3d plots? I'm not proffiecient enough in Python, but I'm wondering if an analogous attribute to collections would be the answer
code to repro this issue:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
fig = plt.figure()
ax = Axes3D(fig)
x = np.linspace(-5, 5, 100)
y = np.linspace(-5, 5, 100)
x, y = np.meshgrid(x, y)
z = x**2 + y**2
s = ax.plot_surface(x, y, z, rstride = 1, cstride = 1, cmap='gray', linewidth=0, antialiased=False)
plt.savefig("3d.pdf")
Error when using collections:
AttributeError: 'Poly3DCollection' object has no attribute 'collections'
Thanks!
