Is there any way to select an object when issuing the command
plotedit(hfig,'on');
I tried to overwrite 'CurrentObject' property but it did not work. There is also a 'CurrentAxes' property, and that did not work either.
Is there any solution?

When you issue plotedit one of the objects on the figure is selected (selection marks are around the object). The object is usually the one which was last selected in previous use of plotedit. I want to say in advance which object should be selected (I know of course the handles of all objects).

OK. Sorry folks, I have found it.
In the defining function:
f=figure;
object=uicontrol(.........,'ButtonDownFcn',{@ButtonDownFcn_Callback,f},'NextPlot','replacechildren',....)
% do it for all objects you define (or you want to select this way)
NextPlot property is necessary only for axes.
and the callback function should do:
function ButtonDownFcn_Callback(hObject,eventdata,hfig)
% hfig=figure; handle to figure containing the objects
% find all axes objects
hhh=findobj(hfig,'Type','axes');
%unselect all objects
[NN,~]=size(hhh);
for i=1:NN
hhh(i).Selected='off';
end
% select the currentobject
hfig.CurrentObject.Selected='on';
plotedit on;
% the object you clicked on will only be selected.
end
and voila, it works.
Note, that plotedit should be switched off in order to use callback again!

f=figure(1);
p=plot(1:10);
ax=findobj(f,'type','axes');

Yes, I said it does not work. But help does not say it is read-only. So I tried.

Are you perhaps looking for inspect?
inspect(axes)
Note, this has gotten a lot better in 18a.

Sorry, no. I explained it above what I mean by "selected".
