Developer console filled with warnings about missing chart series while loading

[AronVanAmmers]

When using the app, many warnings are logged in the developer console. They originate from the DevExpress chart components and contain a message like "The [field name] data field is absent."

I suspect this happens when the chart gets initialised with series, but the data source is still empty.

This is not a new issue, and not critical, but it should be solved.
