If it has nothing to do with Iris then you should either be submitting this example to matplotlib or not submitting it at all. As it is, it is an **Iris example** in the **Iris gallery** that demonstrates how to improve an **Iris plot** of data loaded into Iris. The fact that you go on to use Iris plotting functions and not matplotlib ones adds to this fact. Many of our end users will not care about the fact that Iris plotting functions are wrapped matplotlib ones, so I think you run the risk of confusing the matter further by introducing matplotlib functions that you then do not use in the example.
