# 4D Scatter Plot

Hello,

I am interested in producing a 4 dimensional plot to represent some data.

I picture this as looking like a normal 3d scatter plot with datapoints varying in a color scale which depends on a fourth column of data.

Could anyone help me with this- I have searched google and the matplotlib website and have only found some documentation for a MatLab solution bywhich I am not interested.

Thank you kindly!

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

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

x = np.random.standard_normal(100)
y = np.random.standard_normal(100)
z = np.random.standard_normal(100)
c = np.random.standard_normal(100)

ax.scatter(x, y, z, c=c, cmap=plt.hot())
plt.show()

Angus.
