Create Map from ROI in signal space¶

Use the :func:~.api.plot.plot_roi_map function to create interactive maps defined from ROIs in signal space.

In [ ]:

import hyperspy.api as hs

Create a signal:

In [ ]:

s = hs.data.two_gaussians()

Add 2 ROIs in signal space and map the corresponding signal using :func:~.api.plot.plot_roi_map The ROIs are added to the plot of the signal:

In [ ]:

s.plot()
roi = hs.plot.plot_roi_map(s, rois=2)

Same as above, but plotting the maps in a single figure:

In [ ]:

s.plot()
roi = hs.plot.plot_roi_map(s, rois=2, single_figure=True)
# Choose this figure as gallery thumbnail:
# sphinx_gallery_thumbnail_number = 7

Same as in previous step, but additionally specifying cmap and colors:

In [ ]:

s.plot()
roi = hs.plot.plot_roi_map(s, rois=2, color=["r", "b"], cmap="gray", single_figure=True)
