Using Cubeviz in a Jupyter NotebookΒΆ

To initialize an instance of the Cubeviz app in a Jupyter notebook, simply run the following code in a cell of the notebook:

>>> from jdaviz import CubeViz
>>> cubeviz = CubeViz()

After running the code above, you can interact with the Cubeviz application from subsequent notebook cells via the API methods attached to the cubeviz object, for example loading data into the app as described in Import Data.

Data can also be accessed via the lower-level application interface that connects to the glue-jupyter application level. This is accessed via the .app attribute of the CubeViz helper class. For example:'spectrum-viewer')'flux-viewer')

This code can be used to access data from the different viewers, which is returned as a dictionary. The viewer options in the cubeviz configuration are spectrum-viewer, flux-viewer, uncert-viewer, and mask-viewer. Using the appropriate data label, the data in its native type can be returned from this dictionary like so:'spectrum-viewer')['Subset 1']'flux-viewer')['contents[FLUX]']

Data can also be accessed directly from data_collection using the following code:[0]

Which is returned as a Data object. The data_collection object can be indexed to return all available data (i.e. not just using 0 like in the previous example).
