I would like my Y axis to be named after a String value from a listbox selection. I have many Strings,named Anna, Maria,Eva,etc. I did this so far:
______________________________________________________________________
Locate_list=findobj(gcf,'Tag','Listbox'); % locate listbox
*String_Value* =get(Locate_list,'Value'); % get string number
........
ylabel(['Name:', *String_Value* ]);
______________________________________________________________________
It gives me a Y label with the number of the string in the list. I would like to have the string name itself. For example:
Name: Anna
instead of:
Name: 2

Any ideas?

Figured it out! I had to use
Locate_list=findobj(gcf,'Tag','Listbox'); % locate listbox
String=str2num(get(Locate_list,'String'));
String_Value =get(Locate_list,'Value'); % get string number
figure('...')
.....
.....
ylabel(['Name:', num2str(*String*(*String_Value*)) ]);
And I get a nice label including the text:
Name: Anna , where Anna was in the listbox as a one of the strings :)

In what variable array are the strings stored for the dialog listbox? Use the index returned into that array to retrieve the value...
ylabel(ThatStringArrayOfStrings(String_Value))
The above presumes a cellstring array; use the 2D addressing from with a character array
ylabel(ThatStringArrayOfStrings(String_Value,:))
I don't know gui's well enough but I'd think there's a more direct access to the listbox return value than findobj and get, though? Look thru the examples for guidance there or maybe a GUI guru will drop in...
