Xvalues can't be DBnull?

I have a Datatable as datasource, and the user can pick any of the columns as X or Y. I plot these values using a Fastline series and set TreatNulls to TreatNullsStyle.Skip.
This seems to work if Yvalues contain DBnull values, though if an Xvalue contains a DBnull value Tchart craches as it wants to cast DBnull to Double.
Is this indeed the behavior? Is it possible to also allow DBnull as XValues?
The Dataset can contain many thousands of records so I would prefer not having to filter the copy the dataset and filter it manually before i give it to Tchart as a datasource.

Hello DieterDHoker,

I could reproduce I have added your request to the wish-list with nume with number [TF02014130] to be considered for inclusion in future releases.

Also, I recomend that if you want use DBNulls with XValues you can use Horitzontal Lien (HorizLine).

Thanks,
