Thanks for the good idea! Changing the dataset that you want to plot is probably the easiest option.

Here is my implementation of that to go with my original code.

```python
def change_ds_for_graph(dsA):
    
    ds = dsA.copy()
    
    for varname, da in ds.data_vars.items():
        for attr in da.attrs:
            if attr in ['units', 'long_name']:
                da.attrs[attr] = proper_units(tex_escape(da.attrs[attr]))
                
    for coord in ds.coords:
        for attr in ds.coords[coord].attrs:
            if attr in ['units', 'long_name']:
                da.coords[coord].attrs[attr] = proper_units(tex_escape(da.coords[coord].attrs[attr]))
    
    return ds

Thank you for your comments, I agree that these changes are opinionated, and so probably inappropriate for inclusion in `xarray` itself. 

I guess my motivation was that I could not see a way to loop through the text in a graph and apply some function to it. It might be easier to directly apply these functions to the text before labelling, rather than changing the labels after they are written, but I hope that this will be possible by using the accessor syntax as you suggest.
 
A more general version of this issue would be a method to pass a list of text-sanitizing-functions to `xarray.plot`. 

Thank you for linking to `salem` and `pint-xarray`, I hadn't discovered those packages before, hopefully I will find some useful functionality there.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,697814535

I'll let the others chime in as well, but there are a few things to consider here:
- xarray's plotting capability is not meant to be ""publication ready"" but ""as close as possible to the data"". I.e. units like `degrees_north`, etc. have to stay like this because it unambiguously shows where the data came from and how users can access it from the file, etc.
- in general, making the plots nicer with opinionated defaults like yours would be a nice addition to the xarray ecosystem. It could live in a separate package, and use the [accessor](http://xarray.pydata.org/en/stable/internals.html#extending-xarray) syntax to extend xarray. For example, my own little extension works this way and does opinionated stuff with the accessor: https://salem.readthedocs.io
