Hi, sorry if this is really obvious!

I am trying to interactively move one plot within another figure using drag and drop mouse operations.

I am using the following function to create the interactive behaviour (below):

As you can hopefully see, it allows me to successfully move both a text box or the graph axis around a figure window succesfully and log x + y co-ordinates.

The function is based upon this answer here: https://uk.mathworks.com/matlabcentral/answers/94681-how-do-i-implement-drag-and-drop-functionality-in-matlab

What I am trying to achieve is to move the plot once it has an image stored within it.

I can make the plot contain an image easily using this answer/place a figure within a figure: https://uk.mathworks.com/matlabcentral/answers/60376-how-to-make-an-inset-of-matlab-figure-inside-the-figure#comment_654093

However, when I do so I lose the interactive element! This happens as soon as any content is added to the axis.

I think it may be because the axis and content are stored as seperate objects but I am unsure?

I am aware of the various functions on FEX, Moveit etc etc, however I am trying to do it in this manner as I need to plug this function into a reasonably heavy backend so am trying to avoid messing around making things into patches and so on.

Thanks in advance! And again, sorry if i've missed the obvious, been staring at this for awhile now...

function drag_drop
dragging = [];
orPos = [];
f = figure('WindowButtonUpFcn',@dropObject,'units','normalized','WindowButtonMotionFcn',@moveObject);
a = annotation('textbox','position',[0.2 0.2 0.2 0.2],'String','...','ButtonDownFcn',@dragObject);
a1 = axes('Position',[.7 .7 .2 .2], 'ButtonDownFcn', @dragObject)
    function dragObject(hObject,eventdata)
        dragging = hObject;
        orPos = get(gcf,'CurrentPoint');
    end
    function dropObject(hObject,eventdata)
        if ~isempty(dragging)
            newPos = get(gcf,'CurrentPoint');
            posDiff = newPos - orPos;
            set(dragging,'Position',get(dragging,'Position') + [posDiff(1:2) 0 0]);
            dragging = [];
        end
    end
    function moveObject(hObject,eventdata)
        if ~isempty(dragging)
            newPos = get(gcf,'CurrentPoint');
            posDiff = newPos - orPos;
            orPos = newPos;
            set(dragging,'Position',get(dragging,'Position') + [posDiff(1:2) 0 0]);
            disp(orPos)
        end
    end
end

Try setting 'HitTest','off' for whatever objects you add to the axes. This will allow mouse clicks to pass through to the axes underneath (so that the axes ButtonDownFcn executes), rather than being captured by the new object.
