[Qgis-user] data defined labelling field details?

[Marco Hugentobler]

Hi William

Could it be that data defined x-/y-fields were not enable in your case?

Data defined alignment or rotation is only useful if the label position is data 
defined too (otherwise, the PAL library calculates position and rotation). 

Regards,
Marco
