Extraction of linescan
======================

This example shows how to extract a linescan from a map using a region of interest (ROI).

.. GENERATED FROM PYTHON SOURCE LINES 9-10

Load the data

.. GENERATED FROM PYTHON SOURCE LINES 10-18

.. code-block:: Python

    import lumispy as lum
    import hyperspy.api as hs
    import numpy as np

    cl1 = lum.data.nanoparticles()

    cl2 = cl1.T.mean()
    cl2.data = cl2.data.astype(np.float32)







.. GENERATED FROM PYTHON SOURCE LINES 19-20

First Intialize Line-ROI (:py:class:`hyperspy.api.roi.Line2DROI`) from position (100, 700) to position (900, 100) of width 20 in calibrated axes units

.. GENERATED FROM PYTHON SOURCE LINES 20-25

.. code-block:: Python


    line_roi = hs.roi.Line2DROI(100, 700, 900, 100, 20)
    cl2.plot()
    line_roi2 = line_roi.interactive(cl2, color="red")  # to show the ROI on the plot

Extract data along the ROI as new signal profile by “slicing” the signal and plot the profile

.. GENERATED FROM PYTHON SOURCE LINES 27-31

.. code-block:: Python


    profile = line_roi(cl2)
    profile.plot()
