Hi,

I have a strange problem, I did a uitable and concatenate the rows but it displays the data from row 5. Can someone tell me why? and how to display the data from row 1?

Thanks

Hi,

Yes, it is with GUIDE.

The code is:

      cData = {AInfo, BInfo, CInfo, DInfo, EInfo};  
      old_data=get(handles.infoTable,'data')
      new_data=[old_data;cData]
      set(handles.infoTable, 'data',new_data);

The output is:

old_data =
      ''    ''    ''    ''    ''
      ''    ''    ''    ''    ''
      ''    ''    ''    ''    ''
      ''    ''    ''    ''    ''
new_data =
      ''              ''          ''          ''          ''      
      ''              ''          ''          ''          ''      
      ''              ''          ''          ''          ''      
      ''              ''          ''          ''          ''      
      [1x116 char]    [0.9764]    [0.3566]    [0.1619]    [0.5874]

Any idea why the old_data is giving 4 empty rows?

Thx.

Post an example. Are you using a guide?

Please add all information, which are required to understand the problem, in the original question. Then a reader can get all details by reading the question and not by collecting different informations from comments and answers.

old_data contains empty values, when the uitable contains empty fields only. Currently the posted code does not reveal, why the first row should contain any values.

Maybe you should initialize in your opening function

set(handles.infoTable, 'data',[]);

Hi,

I atached the code, whcih is mainly one uitable and one pushbutton.

Hope it helps.

The output starts from row 5 and not from row 1.

Thanks.

function varargout = untitled1(varargin)
% UNTITLED1 MATLAB code for untitled1.fig
%      UNTITLED1, by itself, creates a new UNTITLED1 or raises the existing
%      singleton*.
%
%      H = UNTITLED1 returns the handle to a new UNTITLED1 or the handle to
%      the existing singleton*.
%
%      UNTITLED1('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in UNTITLED1.M with the given input arguments.
%
%      UNTITLED1('Property','Value',...) creates a new UNTITLED1 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before untitled1_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to untitled1_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".

I am not seeing set(handles.infoTable, 'data',[]); in your untitled1_OpeningFcn
