Create Map from CircleROI in signal space#
Use the plot_roi_map()
function to create interactive maps defined
from a CircleROI
in signal space.
import hyperspy.api as hs
import numpy as np
Create a signal:
rng = np.random.default_rng(0)
data = rng.random(size=(100, 100, 50, 50))
s = hs.signals.Signal2D(data)
Add 2 ROIs in signal space and map the corresponding signal using plot_roi_map()
.
The ROIs are added to the plot of the signal and by default a
RectangularROI
is used
s.plot()
roi = hs.plot.plot_roi_map(s, rois=2)
Same as above but with using CircleROI
with predefined position:
roi1 = hs.roi.CircleROI(cx=25, cy=25, r=5)
roi2 = hs.roi.CircleROI(cx=25, cy=25, r=15, r_inner=10)
s.plot()
roi = hs.plot.plot_roi_map(s, rois=[roi1, roi2])
