Hello!
Can please someone help me with a simple qustions.
1) I have a plot in my GUI and I enabled Data Cursor. Because I have dates on my X, I converted it successfully. But now, I want to add a character(g) to the Y.
Y is a number(mass in grams), so I just want the datatip showing grams next to the mass value.
pos = get(event_obj,'Position');
output_txt = {['Datum: ',datestr(pos(1), 'dd.mmm.yyyy')],...
['Masa: ',num2str(pos(2))]};
2) When I run my GUI, I want it to be in the center of the screen. I used movegui(center), but it did nothing. Where should I even place the command in my GUI code?
3) I want my GUI to open an .xls file in Excel and not in Editor.

Hi,
for 2): what error do you get? You should add something like
movegui(handles.figure1, 'center')
for 3): do something like
[f,p] = uigetfile('*.xls');
winopen(fullfile(p,f))

Thanks man!
It worked!
2) But why is there a command movegui(center) and does not specify anything about handles?
3)When I click on PushButton, it opens the explorer asking me to choose a file. Can I get pass that, so it just directly opens up?

2) That's just like many other functions: if no handle is given, it takes the current figure (e.g. hold). More robust usually is to pass the handle.
3) Of course, if you know the file just write
winopen('C:\MyDatafile.xls')

Hi,
for 1): do you mean this:
output_txt = {['Datum: ',datestr(pos(1), 'dd.mmm.yyyy')],...
['Masa: ',num2str(pos(2)) 'g']};
2) A call to movegui should come into your guiname_OpeningFcn.
3) Don't undertstand the question...

1) Worked like a charm!
2) I've put it in here, but it just pops ERROR.
% --- Executes just before goliGUI is made visible.
function goliGUI_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% Choose default command line output for goliGUI
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
if strcmp(get(hObject,'Visible'),'off')
plot(rand);
end
3) I want to open .xls file in Excel, outside MatLab on PushButton in my GUI. So when I click it, Excel 2007 opens and the file.
Thanks for a quick response!
