Dataview does not contain all categories unless I drill?
I'll provide the answer to this one myself...
When developing (not just using) your own custom visual with a categorical datamapping, you can allow the user to add multiple categories. However, unless the user uses drilling, your dataview will only contain a single category. I.e. your custom visual must test for this by counting the number of categories in the dataview.
Visuals from powerbi itself seem to have an option to open a visual in drilled down mode. A feature not available to custom visuals using the API. This explains the difference my question was about.
Thank you.
