This finally addresses #3745, by providing a replacement for the example plot that was relying on GRIB source data. The new plot uses different data (in netcdf).
Hopefully, the alternative is good enough.

Closes #3745

Thanks @pp-mo! I've tested this locally and I believe the new file demonstrates polar stereographic as well as the old one. I will hold off merging until discussion is complete on SciTools/iris-sample-data#27

Can also confirm that Travis is passing. Link may have been broken by the PR name change.

@pp-mo now that I've merged SciTools/iris-sample-data#27, are you happy that this PR is no longer WIP?

I'm holding off until #3742 is merged as that seems like the less confusing sequence IMO

As expected, #3742 has caused this PR to have a conflict. @pp-mo please could you resolve this so that I can proceed with the merge? Thanks

Thanks @trexfeathers
So, I pushed an extra merge commit to fix the merge problem.
I applied the @abooton method here : producing a manual merge commit to fix problems, instead of rebasing.
Dead easy in this case !

Unfortunately though .. it seems the conflict isn't the whole remaining problem...
What we missed was that the original "green tick" appearing above is actually missing a Travis test (don't ask me why, this continues to happen sporadically).
So, the problem is that we need to release a new iris-sample-data to get this working.
Watch this space ...

SciTools/iris-sample-data#28 refers.
If someone can address that, then I'll cut a new iris-sample-data version 2.3.

Then, of course, we will need another PR to bump the sample-data version to "2.4.0dev".

Actually no, now we need a friendly reviewer on the conda-forge feedstock : conda-forge/iris-sample-data-feedstock#9
Not you or me, as we don't have merge there. Possibly @bjlittle if he gets there first.

Quite a little dance, isn't it ?

Now sorted !

Next to do: check for availability on conda-forge channel, then re-spin here...

@pp-mo I wasn't aware that we did graphics tests on the examples. But looking at the failed tests that clearly is the case and we'll need to make the necessary changes to imagerepo.json and test-iris-imagehash.

Oh bother 😫
It seems we need a new image hash, and a new file in test-iris-imagehash too.
I think I only ran the docs build, not the example tests.

  • so, now that seems obvious !

Sorry, missed your update when I posted my latest.
Yes, for each sourcefile in ./docs/iris/example_code there is a matching runnable test in ./docs/iris/example_tests (though the division into separate subfolders is not preserved).

I just hadn't run them. And of course it wouldn't run on Travis till we got the new sample-data release.

Here we go ... SciTools/test-iris-imagehash#34

"New image hash"

This is going to fail again.
Now failing, as expected.
But should be OK on respin, once SciTools/test-iris-imagehash#34 is merged.
