# Quick Looks¶

Once you’ve loaded a cube, you inevitably will want to look at it in various ways. Slices in any direction have quicklook methods:

>>> cube[50,:,:].quicklook() # show an image
>>> cube[:, 50, 50].quicklook() # plot a spectrum


The same can be done with moments:

>>> cube.moment0(axis=0).quicklook()


## PVSlicer¶

The pvextractor package comes with a GUI that has a simple matplotlib image viewer. To activate it for your cube:

>>> cube.to_pvextractor()
