Series created by DBCrossTab has a differnt format

Hello

TeeChart Pro v2012.06.120613.

For DBCrossTabSource, the master series' properties are not applied to the newly created series, for example, the line pattern, pointer settings.

I guess the "AssignFormat" need to be enhanced for applying the newly introduced properties be copied correctly.

Re: [Bug]TDBCrossTabSource manipulates for 0 instead of NULL

Hi It is a different case. In my case, there is no record at all for region west in year 2001 in dataset, not a 0, or a NULL value.
