Did you follow the documentation here: https://docs.mendix.com/refguide/chart-widgets#1-introduction ?
Basicly create a microflow where you create the series and datapoint (and you could use OQL to retrieve and calculate those) and store the result in the non persistent object which you pass to the widget.

Hi Ronald,
Thanks for your info – yes I followed the info there before but then managed to get it work. After much debugging found that we had different column names as the alias values in the OQL compared to the non-persistent domain object – once those were matched it worked.
I didn’t spot this being a necessity anywhere on the documentation but it obviously makes sense that it is needed!
