In my case I had Coordinates that looked something like this
```
Coordinates:
  * time     (time) datetime64[ns] ...
  * ens      (ens) MultiIndex
  - model    (ens) ""CESM"", ""MIROC"", ...
  - number   (ens) 0, 1, ...
```
and I wanted to do `da.plot(x=""time"", y=""number"")`, but this does currently not work. What I could do is `ds.reset_index(""ens"")` and use the resulting ""non-dimension coordinate"" for plotting.

(Both ""non-dimension coordinate"" and ""MultiIndex"" have some issues, so depending on what I want to do I need one ore the other.)

*which is why I only needed to change the valitity check for `x` and `y` and not the plotting itself","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,594674417

Would it be more intuitive to allow plotting with multiindexes by converting the multiindex  to a vector of strings and passing that to MPL?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,594674417
