GogObject *label = gog_object_add_by_name (GOG_OBJECT (axis), "Label", NULL);

More generally, you can look at the 'static GogObjectRole const roles[]'
in the *_class_init() function for the appropriate class.

You can add as many titles as you want in the same way you add the first
title. This is also true for axis labels.

gboolean gog_object_set_position_flags (GogObject *obj, GogObjectPosition flags, GogObjectPosition mask);
void gog_object_set_manual_position (GogObject *obj, GogViewAllocation const *pos);
