Share data from a function to pushbutton call back in gui

function pushbutton3_Callback(hObject, eventdata, handles)

% hObject handle to pushbutton3 (see GCBO)

% eventdata reserved - to be defined in a future version of MATLAB

% handles structure with handles and user data (see GUIDATA)

i need data1 in this function for several operation

function output_txt = labeldtips(obj,event_obj,hdt)

dcs=hdt.DataCursors;

pos = get(dcs(1),'Position');

output_txt{1} = ['X: ', num2str(pos(1))];

output_txt{2} = ['Y: ', num2str(pos(2))];

data1=pos(2);

Can anyone help me ? Thanks in advance.

Mehedi - if you want data1 to be used by your pushbutton3 callback, then just add this variable to the output parameter list of the function. So something like

 function [data1,output_txt] = labeldtips(obj,event_obj,hdt)
 dcs=hdt.DataCursors;
 pos = get(dcs(1),'Position');
 output_txt{1} = ['X: ', num2str(pos(1))];
 output_txt{2} = ['Y: ', num2str(pos(2))];
 data1=pos(2);

would do the trick. Call it from your callback as

 function pushbutton3_Callback(hObject, eventdata, handles)

 % do stuff

 % call function
 [data1,output_txt] = labeldtips(....);
