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)
  • map signal circleROI
  • Signal
  • Integrated intensity Signal
  • Integrated intensity Signal

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])
