In the example I pass only `norm`  to the plotting function ... 
As suggested by @kmuehlbauer the solution to this issue is to specify the `extend` argument in both the plotting call and `cbar_kwargs`. 
In the example, `extend` was only defined in `cbar_kwargs` (since is an argument also of [mpl.Figure.colorbar](https://matplotlib.org/stable/api/figure_api.html#matplotlib.figure.Figure.colorbar)). Likely we should align the arguments  somewhere in the code with something like this:

```
if extend is None and cbar_kwargs.get(""extend) is not None: 
   extend = cbar_kwargs.get(""extend) 
if extend is not None and ""extend"" not in  cbar_kwargs
   cbar_kwargs[""extend""] = extend 
```

@veenstrajelmer : Adding the `levels=levels` argument (together with `norm`, ... or dropping `norm`) does not correct/change the output figure.
Of course commenting `#da1.data[da1.data>=norm.vmax] = norm.vmax - 1` ""solves"" the issue, but this line of code is what enables to show up **the bug, which is occurring when the array does not contain any value equal to or higher than `norm.vmax `**","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1368027148
