Scoping out example gallery

As discussed at the sunpy coordination meeting it would be good to have some examples on the ndcube docs to show all the fabulous things ndcube can do

This issue is a place where some ideas can be suggested and collated.

So far something along the lines (please say if these are bad and please add some more!):

• [x] How to create a NDCube from a FITS file
• [ ] Creating an NDCube/NDCube sequence with a data cube/data sequence
• [ ] creating gWCS using Extracoords
• [ ] How to slice and plot a NDCube
• [ ] How to crop an NDCube (by index and coords)
• [ ] .....

Please add some more here so that we can have some actionable items!

@wtbarnes @murphp30 if you have any ideas!

I'm working on the first one at the moment

I'm inadvertently working on "Creating an NDCube/NDCube sequence with a data cube/data sequence" at the moment, see #542. I wonder should there be something like "How to do this common task with NDCube and why it's better/more efficient/more fun"? I've no idea how it would work beyond the title though 😬

That initial list covers most of the use cases I was initially thinking about.

Re: How to slice and plot a NDCube, I think this should include the following points

• Adjusting aspect ratio
• Changing plot_axes
• Changing the units of the axes
• Changing the units of the thing we are plotting
