"""
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.

"""

import hyperspy.api as hs

#%%
# Create a signal:
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:
s.plot()
roi = hs.plot.plot_roi_map(s, rois=2)

#%%
# Same as above, but plotting the maps in a single figure:
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``:
s.plot()
roi = hs.plot.plot_roi_map(s, rois=2, color=["r", "b"], cmap="gray", single_figure=True)
