I had ^2.0.2 in my package.json, so when running a clean npm install I got the new 2.1.0
and my chart went from working

to not working (I've set black on the points so we can see them)

The fill doesn't seem to work at all. Any ideas why?
This line in the release notes is telling me you don't follow semver which I really think you should.
I used those in my code so that broke, but I've fixed that so it doesn't seem related to the chart looking weird.
You can now share data between charts. Note that this will require changes if dataset.metadata or dataset.metaDataset were being used. There is now a helper function to retrieve the correct meta data for a given dataset
