Creates a 4D image#

This example creates a 4D dataset, i.e. 2 navigation dimension and 2 signal dimension and plots it.

  • Random 2D image stack Navigator
  • Random 2D image stack Signal
import numpy as np
import hyperspy.api as hs

# Create a 2D image stack with random data
im = hs.signals.Signal2D(np.random.random((16, 16, 32, 32)))

# Define the axis properties

# Give a title
