@adykstra you can probably infer this from our other docstrings, but you'll probably want to add something like this:
```
border : str
    The color of the border to put around the plots. If 'none', no border will be shown.
```
Also, it can probably accept more than just `str` as an argument type -- check the docs for `pyplot`. Then you'd normally make the default whatever it used to be (so as not to change the behavior), but in this case the change is minor and I rather like it without borders, so I'd say go with `border='none'` as the default.
