I found the select command, which should return the name of the selected object via select -g F;%F=
Works with the axis title, the legend and a polyline, but not with the axis itself or the axis label.
BUT:
If I copy the format of the axis label manually, select the axis label in another graph and then use labtalk to paste the format via run.section(file, pasteFormats);
it works. The special tick is where it should be.
So I just need to get the damn label selected with labtalk... ;-)
