how do i save the data from ginput?

This is my script:

% --- Executes on button press in pushbutton5. select finish line function pushbutton5_Callback(hObject, eventdata, handles)

data=[] data(1)=ginput(1); x=data(1){:,1} y=data(1){:,2}

i want to save the x, y points from the ginput, how would i do this?

data = ginput(2);
x = data(:,1);
y = data(:,2);

Or simply:

[x , y] = ginput(2);

I receive this error:

Attempted to access data(:,1); index out of bounds because size(data)=[0,0].

Error in sprintfinish>pushbutton2_Callback (line 101) x = data(:,1);

Error in gui_mainfcn (line 96) feval(varargin{:});

Error in sprintfinish (line 42) gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)sprintfinish('pushbutton2_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

okay it now works however, I cannot refer to it later on in the code it says undefined variable function 'x'

Undefined function or variable 'x'.

Error in sprintfinish>pushbutton3_Callback (line 117) st=x

"later in the code" , does that mean you want to use it other callbacks, if yes you need to store it in the handles structure:

data = ginput(2);
handles.data = data;
guidata(hobject , handles)

[Franchesca]

okay so how would I refer to it later on?

[Dishant Arora]

data = handles.data;
