Hi @dcherian,

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

```
