Hi Stanislaw Wanatowicz ,
We deeply regret for the inconvenience and we would like to let you know that it is not possible to see all the levels, while binding the relational data to itemsource of OlapDataManager through OlapChart.
We don’t provide complete support (like drill down) for IEnumerable type data source binding in OlapChart in WPF platform and further development activities are being handled targeting only OLAP data sources.
Please let me know, if you have any concerns.
Regards,
Niranchana R
