Hi Daniel, There are a couple ways to do this, but the first thing to check -- do you want the data from the simulation, or do you want it from the output image? For instance, with a slice these two things are basically the same. But for a projection, they'll be different, as the projection is the integration along a sight line.
To query along a line, you can either use a data object like ds.ray , which accepts a 3D starting point and ending point, and accessing those values, or you can try using matplotlib's built-in methods for accessing it. You can also access the data buffer by accessing the slice plot's sub-objects. This is described a bit in this document: https://yt-project.org/doc/visualizing/manual_plotting.html There are also methods to export to, for instance, ds9 and glue which you can access on the underlying data_source object. I hope that helps -- and if not, let us know! -Matt On Tue, Mar 12, 2024 at 9:32 PM Daniel Ruvalcaba <[email protected]> wrote: > Hello I am a new user to yt and am also new to python as a coding > language.
