[python #SXQ-775314]: MetPy Cross section vs time analyses

Hello, and thanks for reaching out!

MetPy does not contain any tools specifically for creating pressure-time cross 
sections. However, xarray and Matplotlib should have all the tools you need to 
subset and visualize your data in such a way. Here is a similar existing 
example (that needs some clean-up!) of creating a Hovmoller Diagram: 
https://github.com/Unidata/python-training/blob/master/pages/gallery/Hovmoller_Diagram.ipynb

As you note, MetPy does have a few tools to help you interpolate data 
vertically, but I'm not sure your particular goal here. If you can provide or 
link to some sample data and follow up with the code snippets you're already 
exploring, I'd be glad to help create an example of such a cross section to 
share in our gallery! We may take some time to generate a simplified example of 
this anyway, but please do follow up and let us know how we can further help 
with this. For now, I hope this helps.


All the best,

Drew
