Hi Filipp,
Looks like you are right. I don't see any properties or methods for setting font attributes of an annotation. It appears that the annotations have a similar level of accessible control as cursors, in the fact that neither object has font type or size altering methods exposed. If you would find this functionality useful, my suggestion would be to file a product suggestion for LabVIEW
here.
Cheers,
