Interactive integration of one dimensional signal
=================================================

This example shows how to integrate a signal using an interactive ROI.

.. GENERATED FROM PYTHON SOURCE LINES 8-11

.. code-block:: Python


    import hyperspy.api as hs








.. GENERATED FROM PYTHON SOURCE LINES 12-13

Create a signal:

.. GENERATED FROM PYTHON SOURCE LINES 13-15

.. code-block:: Python

    s = hs.data.two_gaussians()








.. GENERATED FROM PYTHON SOURCE LINES 16-17

Create SpanROI:

.. GENERATED FROM PYTHON SOURCE LINES 17-19

.. code-block:: Python

    roi = hs.roi.SpanROI(left=10, right=20)








.. GENERATED FROM PYTHON SOURCE LINES 20-23

Slice signal with roi with the ROI. By using the `interactive` function, the
output signal ``s_roi`` will update automatically.
The ROI will be added automatically on the signal figure:

.. GENERATED FROM PYTHON SOURCE LINES 23-28

.. code-block:: Python

    s.plot()
    sliced_signal = roi.interactive(s, axes=s.axes_manager.signal_axes)
    # Choose the second figure as gallery thumbnail:
    # sphinx_gallery_thumbnail_number = 2

.. GENERATED FROM PYTHON SOURCE LINES 29-30

Create a placeholder signal for the integrated signal and set metadata:

.. GENERATED FROM PYTHON SOURCE LINES 30-33

.. code-block:: Python

    integrated_sliced_signal = sliced_signal.sum(axis=-1).T
    integrated_sliced_signal.metadata.General.title = "Integrated intensity"








.. GENERATED FROM PYTHON SOURCE LINES 34-37

Create the interactive computation, which will update when the ROI ``roi`` is
changed. wWe use the ``out`` argument to place the results of the integration
in the placeholder signal defined in the previous step:

.. GENERATED FROM PYTHON SOURCE LINES 37-45

.. code-block:: Python

    hs.interactive(
        sliced_signal.sum,
        axis=sliced_signal.axes_manager.signal_axes,
        event=roi.events.changed,
        recompute_out_event=None,
        out=integrated_sliced_signal,
    )
