Ellipse markers#

Create a signal

import hyperspy.api as hs
import numpy as np

# Create a Signal2D with 2 navigation dimensions
rng = np.random.default_rng(0)
data = np.ones((25, 25, 100, 100))
s = hs.signals.Signal2D(data)

This first example shows how to draw static ellipses

# Define the position of the ellipses
offsets = rng.random((10, 2)) * 100

m = hs.plot.markers.Ellipses(
    widths=(8,),
    heights=(10,),
    angles=(45,),
    offsets=offsets,
    facecolor="red",
    )

s.plot()
s.add_marker(m)

Dynamic Ellipse Markers#

This first example shows how to draw dynamic ellipses, whose position, widths heights and angles depends on the navigation coordinates
