I could not find a comprehensive graphics object types list that could be especially useful to find an modify objects in matlab plots such as:
findall(gcf,'Type','Line'); %get all line objects in the current figure
To be more precise: I'm looking for a list of possible input after the argument 'Type'.
I am not aware of a way to get the comprehensive list, but you can get the list of types for existing objects:
types = unique(get(findall(gcf, '-property', 'Type'), 'Type'));
Practically I think this is enough, since we are not interested in those non-existing objects.
