Current docstring for `imshow` does specify this. Closing.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,258913450

I had a look at your data, and there are two issues that imshow cannot handle well:
- your data isn't well centred (lons go from -300 to 60, which explains the shape of your image on the globe). This wouldn't be a big deal if it wasn't for the other problem, which is:
- your latitude data isn't regular.
```python
plt.plot(ds.lath[1:].values - ds.lath[:-1].values)
```
Gives:
which is quite... interesting.
Anyways, ``imshow`` is so much faster because it needs regular, nicely sorted data. In your case I don't think there is much other choice than ``pcolormesh`` or ``contourf``... Note also that plotting on Robinson is slower than plotting on a plate carree projection.","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,258913450
