I load the dataet,table and table data via an API.
On the Cloud I go to the Steamable data sources. (Dutch GUI - I may not have the correct English name for that.)
I create a new chart. Line Diagram. I drag a date field to the AS part of the chart.
If I do that with a table that I created in the Desktop then I get the very useful Year Quarter Month Day helper columns underneath the Date field that I just dropped.
With data loaded from the API I do not get these helper fields - the date stays as a flat date. (And lets be honest - noone is going to do a serious line chart on single dates.)
The workaround would be to load year, year-month and year-quarter fields. But that is not very user firendly....
