Invalid Rgba Arg "#" In Matplotlib

I can't figure out how to use colours while trying to create a scatter plot in matplotlib. I'm trying to plot multiple scatter plots with different colour points to show the cluste

Solution 1:

Its just a simple typo: You are missing a comma at the end of the first line of colors (between '#22222f' and '#eeeff1'), which means two entries get concatenated into a string that matplotlib can't interpret as a color.

foriincolors:
    printi#12efff#eee111#eee00f#e00fff#123456#abc222#000000#123fff#1eff1f#2edf4f#2eaf9f#22222f#eeeff1#eee112#00ef00#aa0000#0000aa#000999#32efff#23ef68#2e3f56#7eef1f#eeef11

If you add the comma in there, all seems fine.

To get your "MCVE" to work, I had to add the module imports, and assume that groups has a length the same as colors:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np

colors=['#12efff','#eee111','#eee00f','#e00fff','#123456','#abc222','#000000','#123fff','#1eff1f','#2edf4f','#2eaf9f','#22222f',
        '#eeeff1','#eee112','#00ef00','#aa0000','#0000aa','#000999','#32efff','#23ef68','#2e3f56','#7eef1f','#eeef11']

C=1
fig = plt.figure()
ax = fig.gca(projection='3d')

groups = range(len(colors))
for fgroups in groups:
   X=[np.random.rand(50),np.random.rand(50),np.random.rand(50)]
   Y=[np.random.rand(50),np.random.rand(50),np.random.rand(50)]
   Z=[np.random.rand(50),np.random.rand(50),np.random.rand(50)]
   C=(C+1) % len(colors)
   ax.scatter(X,Y,Z, s=20, c=colors[C], depthshade=True)
plt.show()
