Filled Circle Markers#
Create a signal
import hyperspy.api as hs
import matplotlib as mpl
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 filled circles
# Define the position of the circles
offsets = rng.random((10, 2)) * 100
m = hs.plot.markers.Points(
sizes=20,
offsets=offsets,
facecolors="red",
)
s.plot()
s.add_marker(m)
Dynamic Filled Circle Markers#
This second example shows how to draw dynamic filled circles, whose size, color and position change depending on the navigation position
s2 = hs.signals.Signal2D(data)
offsets = np.empty(s.axes_manager.navigation_shape, dtype=object)
sizes = np.empty(s.axes_manager.navigation_shape, dtype=object)
colors = list(mpl.colors.TABLEAU_COLORS.values())[:10]
for ind in np.ndindex(offsets.shape):
offsets[ind] = rng.random((10, 2)) * 100
sizes[ind] = rng.random((10, )) * 50
m = hs.plot.markers.Points(
sizes=sizes,
offsets=offsets,
facecolors=colors,
)
s2.plot()
s2.add_marker(m)
