I would like to know if there is a way to get the standard side by side diff view in magit. That is, instead of seeing the old code chunk and the new one one after the other, I'd like to see them on the same horizontal alignment.
The Emacs package for doing this is named Ediff and Magit supports Ediff. To get started press e on the change for which you want to see the side-by-side comparison. You might also have to use E occasionally to tell Ediff/Magit explicitly what you want to compare.
Also see the Ediff manual and the node about Ediff in the Magit manual.
e, and you can configure ediff to display side-by-side views by default. – phils Nov 18 '16 at 10:29
