```
da.plot.pcolormesh('lon', 'lat', shading='gouraud', infer_intervals=False)
```
does work. Would be nice if `shading='gouraud'` worked by default though.

I guess the problem is that 'gouraud' needs the coordinate positions at the grid points, and I assume `infer_intervals=True` is creating coordinate values at the grid-cell corners (so an n x m DataArray is plotted using coordinates with lengh (n+1) and (m+1). I haven't looked into what `infer_intervals` actually does though. Would it be safe to just turn it off if `shading='gouraud'` is used?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,453126577

That's confusing because this works:

```python
plt.pcolormesh(da['lon'].values, da['lat'].values, da.values, shading='gouraud')
```

but it looks like matplotlib is the problem, I'll close this.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,453126577
